I saved the `file_types.json` file and got a diff because it had some
trailing whitespace. I ran
[`lineman`](https://github.com/JosephTLyons/lineman) on the codebase.
I've done this before, but this time, I've added in the following
settings to our `.zed` local settings, to make sure every future save
respects our desire to have consistent whitespace formatting.
```json
"remove_trailing_whitespace_on_save": true,
"ensure_final_newline_on_save": true
```
Release Notes:
- N/A
Release Notes:
- Extracted lua language support into an extension, and improved Lua
highlighting and completion label styling.
