Problem is that it won't actually use the actions we are changing until they are in main, so the result of the workflow is not that useful.

Note that both project version an project name actions are so similar that could be parametrized.

We are using pdm (and setuptools if there instead of a pyproject.toml there is a setup.py) to extract the information.
pdm works even if the pyproject.toml has another build system.
In our tests we went to the folder setup.py is in, since modern versions of setuptools read first pyproject.toml.
