push releases to PyPI

[soxofaan]

Some public projects like https://github.com/Open-EO/openeo-aggregator and https://github.com/Open-EO/openeo-test-suite depend on openeo-python-driver. The package is not available on PyPI, but only on VITO artifactory. This requires the user to link to VITO artifactory (e.g. pip ... --extra-index-url with appropriate URL).

This is extra cruft to document in various places, and it is not always easy to get it right in some tooling contexts.

I think we should push some releases from time to time to PyPI

documentation example where I had to add the extra-url: https://github.com/Open-EO/openeo-test-suite/blob/7dd98b1737a3d241974400a1e7f30778835490fa/README.md?plain=1#L66-L73

I decided to already push a release to avoid other people stealing our package name on pypi:
https://pypi.org/project/openeo-driver/0.83.0a1/
