Issue 2977: LuaLS autodoc is including global table in output md/json files

[codrod]

Fixes ISSUE 2977

The LuaLS autodoc is exporting the LuaCATS meta definition files for the builtin Lua language features. I added a new function getExportableGlobals() since we do want to track the builtin globals but not export them. I also updated the default export.gatherGlobals() to use the new getExportableGloblas() function instead of getAllGlobals().

Summary of Changes

Hello @codrod, 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 addresses a bug in the LuaLS autodoc feature that caused it to export internal LuaCATS meta definitions alongside user-defined globals. The changes introduce a mechanism to differentiate between internal and exportable global definitions, ensuring that the generated documentation accurately reflects only the intended public API.

Highlights

• Fix Autodoc Export: Resolves an issue where LuaLS autodoc was incorrectly including internal LuaCATS meta definitions in its output documentation files.
• New Filtering Function: Introduces a new function, vm.getExportableGlobals(), which filters the complete list of global definitions to return only those intended for export, excluding internal meta definitions.
• Updated Global Gathering Logic: Modifies the export.gatherGlobals() function to utilize the newly introduced vm.getExportableGlobals(), ensuring that only relevant and public global definitions are processed for documentation generation.
