Subject: Update tree-sitter-erlang and highlights

A few changes:

* 0-arity type specs like the following previously would not have the
  expected 'variable.parameter' highlighting for the return type:

    -spec foo() -> Value when Value :: term().

* Highlight module, type and function docs as documentation comments
  and inject markdown into them.

* Replace `#match?` predicates with `#any-of?` where possible.

* Remove custom auto-pairs. Now that Erlang uses markdown for
  documentation, the asciidoc-style backtick-singlequote pair is no
  longer useful.
