Does not work with RTC on JupyterLab 4.0?

Testing 0.55.0a0 on binder with RTC on:

https://mybinder.org/v2/gist/krassowski/847732eb6c16e168fb4c0b16d9706142/HEAD?urlpath=lab

RTC: is not a Git repository. To use Git, navigate to a local repository, initialize a repository here, or clone an existing repository.

Clicking Initialize:

Traceback (most recent call last): File "/srv/conda/envs/notebook/lib/python3.10/site-packages/jupyterlab_git/git.py", line 184, in execute code, output, error = await current_loop.run_in_executor( File "/srv/conda/envs/notebook/lib/python3.10/concurrent/futures/thread.py", line 58, in run result = self.fn(*self.args, **self.kwargs) File "/srv/conda/envs/notebook/lib/python3.10/site-packages/jupyterlab_git/git.py", line 145, in call_subprocess process = subprocess.Popen( File "/srv/conda/envs/notebook/lib/python3.10/subprocess.py", line 971, in __init__ self._execute_child(args, executable, preexec_fn, close_fds, File "/srv/conda/envs/notebook/lib/python3.10/subprocess.py", line 1863, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: '/home/jovyan/rtc:'

@krassowski Using jupyterlab 4.3.4, (jupytext 1.16.6), collaboration-extension 3.1.0, and jupyterlab-git 0.50.2, the issue is back for me:

RTC: is not a Git repository. To use Git, navigate to a local repository, initialize a repository here, or clone an existing repository.

If I install the latest jupyterlab and RTC versions pip install --pre "jupyterlab>=4.4.0a2" "jupyter-collaboration>=4.0.0a0", the RTC tag disappears, but jupyterlab-git is still unable to recognize the git repo. It now says:

You are not currently in a Git repository. To use Git, navigate to a local repository, initialize a repository here, or clone an existing repository.

.. even if I am in a git repo. I guess this has something to do with the new/updated content-providers API or workspaces (?)
