docs: Improve Lua documentation generation

[usagirei]

Purpose of change (The Why)

Lua Documentation page is hard to read / use / navigate

Draft for now while i finish validating the changes

Describe the solution (The How)

• Places docstrings inside a blockquote
• Hides operators (__eq, __lt, __tostring, etc)
• Distinguish free functions from methods
  • Add a note regarding functions / methods in Lua
• Adds clickable links in function signatures / member types for ease of navigation
• Show demangled names for types without mappings
  • Goodbye St3setINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESt4lessIS5_ESaIS5_EE

Checklist

Mandatory

• I wrote the PR title in conventional commit format.
• I ran the code formatter.
• I linked any relevant issues using github keyword syntax like closes #1234 in Summary of the PR so it can be closed automatically.
• I've committed my changes to new branch that isn't main so it won't cause conflict when updating main branch later.

[autofix-ci]

Autofix has formatted code style violation in this PR.

I edit commits locally (e.g: git, github desktop) and want to keep autofix

1. Run git pull. this will merge the automated commit into your local copy of the PR branch.
2. Continue working.

I do not want the automated commit

1. Format your code locally, then commit it.
2. Run git push --force to force push your branch. This will overwrite the automated commit on remote with your local one.
3. Continue working.

If you don't do this, your following commits will be based on the old commit, and cause MERGE CONFLICT.

If I understand correctly, the argument to to_degrees is hidden because we're calling it with colon, so print(Angle.from_radians(3):to_degrees())

Yep, that's a typo, I'll update it
