404 when publishing the package to npm

[jtpio]

Description

While testing the Jupyter Releaser with a JupyterLab prebuilt extension (Python + npm), the Publish Release workflow (example run) would fail to upload the tarball to npm:

This package was already available on npm before.

Updating the workflow with the following diff (as mentioned in jupyterlab/extension-cookiecutter-ts#162 (comment)) helped going through:

Reproduce

It should be possible to reproduce by:

• creating a new extension from the cookiecutter
• go through the jupyter releaser process

Expected behavior

The publish workflow should not fail publishing the package.
