GH Actions: Deploy sdists to PyPI

[mkoeppe]

We extend the sdist.yml workflow from #32403 so that it builds sdists for PyPI using make pypi-sdists (from #29039).
This is run on release tags.

When the secret SAGEMATH_PYPI_API_TOKEN exists and the sdists were successfully created, it then proceeds to publish the sdists to PyPI using https://github.com/pypa/gh-action-pypi-publish

At the moment, the secret SAGEMATH_PYPI_API_TOKEN is only available in the repository https://github.com/mkoeppe/sage; in response to a release tag pushed to it, the workflow has successfully built the 9.5.beta6 release sdists (+ this branch): https://github.com/mkoeppe/sage/runs/4200645206?check_suite_focus=true and deployed to PyPI (see, for example https://pypi.org/project/sagemath-standard/9.5b6/)

Later we can move the deployment to https://github.com/sagemath/sage, simply by providing a secret SAGEMATH_PYPI_API_TOKEN to it. (We may want to add a safety check to the workflow that avoids pushing a release that hasn't had a release candidate.)

OK, make pypi-sdists does seem to work.

Update: I have added the secret SAGEMATH_PYPI_API_TOKEN to https://github.com/sagemath/sage; using it, the GH Actions workflow running there has just uploaded source distributions to PyPI (https://github.com/sagemath/sage/runs/4769340060):

https://pypi.org/project/sage-setup/9.5rc0/

https://pypi.org/project/sage-conf/9.5rc0/

https://pypi.org/project/sage-sws2rst/9.5rc0/
