workspace: Do not scan for .gitignore files if a .git directory is encountered along the way (#3135)

Partially fixes zed-industries/community#575

This PR will see one more fix to the case I've spotted while working on
this: namely, if a project has several nested repositories, e.g for a
structure:
/a
/a/.git/
/a/.gitignore
/a/b/
/a/b/.git/
/a/b/.gitignore

/b/ should not account for a's .gitignore at all - which is sort of
similar to the fix in commit #c416fbb, but for the paths in the project.

The release note is kinda bad, I'll try to reword it too.
- [ ] Improve release note.
- [x] Address the same bug for project files.

Release Notes:
- Fixed .gitignore files beyond the first .git directory being respected
by the worktree (zed-industries/community#575).
