Autocomplete: Add option to disable inside code comments

[philipp-spiess]

Closes #3038

Adds a new user config option to prevent completions inside code comments.

@valerybugakov I didn't get the test to run since the intent detection is never run because the parser cache is always empty even though I ran initTreeSitterParser(). Do you know how we can get this enabled in unit tests? I would expect a call to provideInlineCompletions to preload the parser cache if we have called initTreeSitterParser before but I don't think this happens right now. Perhaps because we query it before the stuff inside get-inline-completions but we do call into tree sitter before that so I think this should work. 😄

Can we get this for jetbrains IDEs?

Comment completion really grinds my gears as I use it to brainstorm :|

[sjurgis]

@philipp-spiess any chance you can point me how to use this setting in Jetbrains IDEs?

[philipp-spiess]

@sjurgis I'll defer to @pkukielka but chances are we don't have the setting there yet.

We do not support it yet but it should be a quick job to add it.
@taylorsperry @kalanchan can prioritise it

[sjurgis]

@taylorsperry @kalanchan that would be a nice differentiator as no other assistant supports this...
