Use trusted publisher with PyPi and blessed action

See https://docs.pypi.org/trusted-publishers/using-a-publisher/ and
https://github.com/pypa/gh-action-pypi-publish. This avoids the need for
an upload token after having configured our GitHub action as trusted
publisher in our PyPi account.

All API tokens have been removed from the account.
