Hi!

Thanks a lot for maintaining this package.
I've just installed this package and when I run `jupyter lab`, I get the
following warning:


$ jupyter lab
Fail to get yarn configuration. Expecting value: line 1 column 1 (char 0)
[W 2025-02-28 11:37:57.924 ServerApp] jupyterlab_jupytext | error adding extension (enabled: True): The module 'jupyterlab_jupytext' could not be found (No module named 'jupyterlab_jupytext'). Are you sure the extension is installed?

The website of jupytext advertises a jupytext menu to pair notebooks,
etc. But it does not show, maybe because of that missing piece of code?
It seems to be included in the version 1.16.7 (whereas it was before an
independent npm module
https://www.npmjs.com/package/jupyterlab-jupytext).


Thanks in advance.
Cédric
