IMPORTANT: While you're welcome to submit PR's for this (or I may if I get some time) - I actually ended up finding a more feature-full extension for wrapping comments after publishing this. I suggest you check out Rewrap for better comment auto-wrapping support.

Easily re-wrap comments to a given line width.

Turns this:

// this is
// my comment that
// does not wrap properly

Into this:

// this is my comment that does not wrap
// properly

Supports:

• ✅ Standard (JavaScript/TypeScript/Java etc.) style comments ( // )
• ✅ Block comments ( /* */ )
• ✅ Dart-doc comments ( /// )
• ❌ Anything else (Python, bash etc.) yet

The default wrap length is 80 - it can be customized with user setting commentWrap.printWidth:

{
  "commentWrap.printWidth": 120
}

This extension is in the very early stages of development (mostly a proof-of-concept at this stage, put together in about 15 minutes) so may not be fully functional.
