Use standardized [project] table in pyproject.toml

[hroncok]

This allows us to swap the build backend more easily in RHEL, where we don't have poetry-code.

This requires poetry-core >= 2 because older poetry did not support this.

Also, replace the value of the license text with a SPDX identifier as documented in https://python-poetry.org/docs/pyproject/#license
Otherwise, poetry-core injects a Other/Proprietary License classifier. (Note that poetry-core does not yet support PEP 639 fully).

This change creates s slight change in the metadata, comments inline.

Thank you! Tested it with uv, works great.

Merged in 9c6d254.

-Requires-Python: >=3.9,<4.0

This doesn't make sense to me. I didn't take this over. It would mean, it requires any Python 3.9 version, but not above. Or do I understand incorrectly?

This doesn't make sense to me...

It's the same thing in different notation.

[hroncok]

~=3.9 means it requires any Python 3 version at least 3.9
