Unannotated local function diagnostic

[NathanSnail]

Currently you can check this for global functions and exported locals but not normal locals. This adds this (disabled by default).

Summary of Changes

Hello @NathanSnail, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the static analysis capabilities by introducing a new diagnostic, missing-local-doc, which specifically targets local functions lacking proper documentation. This feature aims to improve code quality and maintainability by encouraging comprehensive annotation of all function types, ensuring consistency with existing checks for global and exported local functions.

Highlights

• New Diagnostic: missing-local-doc: A new diagnostic has been introduced to identify local functions that are missing comments, parameter annotations, or return annotations. This expands the existing documentation checks beyond global and exported local functions.
• Default Disabled: The newly added missing-local-doc diagnostic is disabled by default, allowing users to opt-in to this check as needed.
• Localization Support: Messages for the new diagnostic have been added across various language locales, though some translations are marked as 'TODO' and will require future updates.
• Comprehensive Testing: Dedicated test cases have been added to ensure the correct functionality and detection of undocumented local functions by the new diagnostic.

I'm not sure how to run build-doc.lua, so that needs doing.
