pyright still reports PathLike as unknown #1620

With sample code like

from git.repo import Repo
repo = Repo(root_of_my_repo)
print(f'repo working dir: {repo.working_tree_dir}')
print(f'is repo dirty ?: {repo.is_dirty()}')

I see VS Code / pylance / pyright messages like these (shortened for better readability):

Type of "working_tree_dir" is partially unknown
  Type of "working_tree_dir" is "Unknown | None"

Type of "is_dirty" is partially unknown
  Type of "is_dirty" is "(index: bool = True, ..., path: Unknown | None = None) -> bool"

both of which seem to be caused by the type of PathLike to be unknown.

However, PathLike clearly is properly defined at

Also, in general, I see from #1095 that full type support has been added to GitPython two years ago - and some detail of this very PathLike issue seems to have been addressed in #1473 about 13 months ago.

AFAICT, I use the latest versions for anything involved:

GitPython: 3.1.32
macOS:     13.4.1
Python:    3.10.12
Pylance:   v2023.7.40 (VS Code extension)
pyright:   1.1.318

Why am I still seeing these pyright issues ?
Do I need to do anything special to get GitPython type support ?
Could there anything wrong with my setup ?
(Using the same setup (e.g. pyright conf) as in 10+ similar projects with no problems, but you never know...)

Really puzzled here and would be really grateful for any advice.

Thank you very much.
