Remove the .txt suffix from tutor

The tutor file is loaded as .txt which can potentially spawn a
language server. Then the path is unset, but the LS remains active.
This can cause panics since updates are now submitted for a doc
with no path.

As a quick workaround we remove the extension which should avoid
detection.

Fixes #3730

+                 A post-modern modal text editor.
+_________________________________________________________________
+
+ Welcome to the Helix editor! Helix is different from editors
+ you might be used to in that it is modal, meaning that it has
+ different modes for editing text. The primary modes you will
+ use are Normal mode and Insert mode. While in Normal mode, the
+ keys you type won't actually type text. Instead, they will
+ perform various actions with the text. This allows for more
+ efficient editing. This tutor will teach you how you can make
+ use of Helix's modal editing features. To begin, ensure your
+ caps-lock key is not pressed and hold the j key until you reach
+ the first lesson.

+          j       * j looks like a down arrow
+          ↓
+
+ The cursor can be moved using the h, j, k, l keys, as shown
+ above. The cursor/arrow keys will also work, but it is faster
+ to use the hjkl keys as they are closer to the other keys you
+ will be using. Try moving around to get a feel for hjkl.
+ Once you're ready, hold j to continue to the next lesson.

+
+ Note: If you want to move the cursor while in Insert mode,
+       you may use the arrow keys instead of exiting and
+       reentering Insert mode.
+ Note: The status bar will display your current mode.
+       Notice that when you type i, 'NOR' changes to 'INS'.

+=================================================================
+
+ As you saw, you can type i to enter Insert mode at the current
+ position of the cursor. There are a few other ways you can
+ enter Insert mode at different locations.
+
+ Common examples of insertion commands include:
+   i - Insert before the selection.
+   a - Insert after the selection. (a means 'append')
+   I - Insert at the start of the line.
+   A - Insert at the end of the line.
+
+ 1. Move to anywhere in the line below marked -->.
+ 2. Type A (<SHIFT> + a), your cursor will move to the end of

+=================================================================
+
+ Type w to select forward until the next word.
+
+ The d key doesn't actually delete the character at the cursor,
+ it deletes all selected text. Your cursor is like a
+ single-character selection.
+
+ 1. Move the cursor to the line below marked -->.
+ 2. Move to the beginning of a word that needs to be deleted.
+ 3. Type w to select until the beginning of the next word.
+ 4. Type d to delete the selection.
+ 5. Repeat for all extra words in the line.

+=================================================================
+
+ As you saw, typing w moves the cursor forward until the start
+ of the next word, selecting the text traversed. This is useful
+ for moving around text and for selecting text to operate on.
+
+ Some common motions include:
+   w - Move forward to before the beginning of the next word.
+   e - Move forward to the end of the current word.
+   b - Move backward to the beginning of the current word.
+
+ The w,e,b motions also have counterparts - W,E,B - which
+ traverse WORDS instead of words. WORDS are only separated by
+ whitespace, whereas words can be separated by other characters
+ in addition to whitespace.
+
+ All of these motions select the text they traverse.
+

+
+ Type c to change the current selection.
+
+ The change command deletes the current selection and enters
+ Insert mode, so it is a very common shorthand for di.
+
+ 1. Move the cursor to the line below marked -->.
+ 2. Move to the start of an incorrect word and type w to
+    select it.
+ 3. Type c to delete the word and enter Insert mode.
+ 4. Type the correct word.
+ 5. Repeat until the line matches the line below it.

+ 2. Type 2w to move 2 words forward.
+ 3. Type 3e to move to the end of the third word forward.

+ Type v again or <ESC> to return to Normal mode

+ 1. Move the cursor to the line below marked -->.
+ 2. Move to the F of FOO and type v2w to select the two words.
+ 3. Type d to remove the two words. Notice d returns you to

+ 1. Move the cursor to the second line below marked -->.
+ 2. Type x to select the line, and d to delete it.
+ 3. Move to the fourth line.
+ 4. Type x twice or type 2x to select 2 lines, and d to delete.

+ --> 4) I have a car,
+ --> 5) Clocks tell time,
+ --> 6) Sugar is sweet,

+
+ Note : X works similarly to x although it doesn't extend to

+
+ Sometimes, you want to deselect without having to move the
+ cursor(s). This can be done using the ; key.
+
+ 1. Move the cursor to the line below marked -->.
+ 2. Use the motions you have learned to move around the line,
+    and try using ; to deselect the text after it is selected
+    by the motions.

+
+ Note: Whenever you delete or change text, Helix will copy the
+       altered text. Use alt-d/c instead to avoid this.
+ Note: Helix doesn't share the system clipboard by default. Type
