Convert setup.py to pyproject.toml

[pjonsson]

The same files are included before/after
when doing "python3 -m build" on
my machine.

I can't see the log from continuous-integration/jenkins/pr-head, so not sure why that is red.

      GIVEN VALUE:
          "Apache-2.0"

as far as I understand the license field should not be a string but a mapping with field "text" containing that string.
This is probably because the build chain used here is stuck at outdated conventions

• Drop support for Python 3.8 #717

@soxofaan ok, this revision of the PR works in a Python 3.8 container for me, and I've rebased to latest master.

Still red in the CI despite building locally, so I'm guessing the CI logs that I can't see are trying to run uv run pytest after installing the tests dependencies.

Accepted any version of sphinx-autodoc-typehints for Python versions that have reached end of life, and skipped openeo_pg_parser_networkx/openeo_processes_dask[implementations] on Python 3.8: https://github.com/Open-EO/openeo-python-client/compare/15d8ce848ba2ec05ead03de7db0a5398b6d0ce4f..c18db737723efc375efd4d75916f1ec87a470eff and after that I can run the tests in the Python 3.8 container locally as well (and they pass).

Apparently still red, but I can't guess what the CI does next, so I need to see some more logs.
