Change Language Config to Fix Indents

[Durbatuluk1701]

Couple Changes Here:

• Change the language configuration files to .language-configuration.json (as suggested by lang guide)
• Modify the language configuration to address Incorrect Indentation with Show Proof. #247 (manual proof indentation with negative lookbehind)
• Modify the wordPattern definition to correctly identify identifiers in Rocq (items with a ' within them before would not be correctly suggested by intellisense)
• Added some auto-indent features for Sections, Module Types, and Modules.

Of Note:

• Changes were made to make it so that match statements do not auto-indent (related to Bad Indentation with match ... end #248), but I am not sure the solution is optimal? I am seeking feedback if we think the behavior exhibited below is better or worse than the current approach?

I still believe #158 would be helpful (and could work on addressing it in the future), but I think hopefully these changes would make some of the default indentation that occurs while typing better

I believe this is already an improvement so I'll merge ! Thanks !
