Documentation generation hotfixes

[ischeinkman]

Hotfix for 2 bugs in the teal environment generation algorithm:

• Fixed fields not being deduped correctly because Vec::dedup only dedupes consecutive duplicate items. This was done by sorting the fields list beforehand.
  • Also deduped static fields while I was at it, though I'm not sure if those are used?
• Fixed the algorithm not properly escaping record fields/functions/methods/etc that share the name of an existing Lua/Teal keyword. This was coming up since the Uuid record has a function called nil for making an all-zero uuid.

Note that this still doesn't completely fix Teal document generation when using the default Bevy APIs since they're still missing a definition for ReflectedValue, but I'll likely need some guidance on that and will split that off to a separate PR.

Tested it works great,

for the ReflectedValue i had to add .process_type::() crates/bevy_script_api/src/core_providers.rs get_doc_fragment
