Automated PIP package upload fails

[mwouts]

Jupytext 1.13.1 should have been uploaded to PIP a few days ago, but the corresponding run ended in error.

Also the following warnings are emitted by jupyter_packaging before the error

• DeprecatedWarning: create_cmdclass is deprecated as of 0.8 and will be removed in 1.0.
• DeprecatedWarning: install_npm is deprecated as of 0.8 and will be removed in 1.0. Use npm_builder and wrap_installers

Here is an extract of the logs:

Locally I am able to build a local version of the package, however it includes the node_modules and is thus way too big (43M), which reminds me of #730.

The issue disappeared and jupytext==1.13.1 was just uploaded to pip thanks to this run of the CI: https://github.com/mwouts/jupytext/runs/4144722117
