Update dependency lock file 2024/06

[glatterf42]

Looking at #93, I noticed that I was using an outdated version of pydantic locally. So this PR updates the dependency lock file that was automatically created by running poetry update locally. No additional changes are required :)
Most notably, everything works even without warnings after bumping to numpy 2.0.0.

Well, so much for the 'no changes required' part. It seems that already with poetry 1.7.0, 'setuptools' was no longer installed per default. I don't know why it was removed now on my local system, but if we won't to keep it around (which is required by our docs-build-process), we should include it as an explicit dependency.

pandas does not specify upper bounds for numpy, even though some fairly recent versions of pandas don't support numpy 2.x. We test these versions by pinning pandas, and we only pin pandas after initially installing everything as normal. This installs numpy 2.x, but then only pandas is downgraded, leading to a binary incompatibility with numpy.
So at the moment, this "legacy pandas step" is now also pinning numpy 1.26.4, which is the latest version before 2.0.0. Please let me know if this is acceptable.

Also, add color support to pytest's GHA output because
