Add a release job to publish on pypi on github tag creation

[Pierre-Sassoulas]

Similar to what is done in pylint (we could test that with alphas first, when releasing the last version only compatible with pylint 2).

PYPI_API_TOKEN is created. LGTM.

Does that create manylinux wheels for all Pythons?

... or do we need my humongous matrix:?

[Pierre-Sassoulas]

It create a wheel for all versions, see https://pypi.org/project/pylint/#files. Not sure if it's the best possible but it works well enough (let me know if there's way to make it better though)

No, pylint looks perfect. py3-none-any.whl
