introspectComments does not play nice with tab indentation

[chromey]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

If tab-based indentation is used in the codebase (e.g. prettier config "useTabs": true), introspectComments does not accurately parse comments. For example, descriptions have leading * characters that are interpreted as bullets, and tsdoc tags are not stripped away.

Minimum reproduction code

I will attach a PR with a test case shortly, let me know if you need anything else.

Steps to reproduce

Expected behavior

introspectComments should work identical for space and tab-based indentation
