fix: remove duplicated `ui.help` in themes

the bottom value is used, so i've removed the top `ui.help` values from all themes

also, the values are not merged, so:

```toml
"ui.help" = { modifiers = ["reversed"] }
"ui.help" = { fg = "white", bg = "black" }
```

is equal to:

```toml
"ui.help" = { fg = "white", bg = "black" }
```
