Updates GH Actions for a number of reasons, one of them is avoiding technical debt. Another reason is expressed in #2920.

Also, I put the python version at the top of ci/requirements-*.yml files to have them readily available.

Adds numba to 3.14 requirements.

I'm still deciding on whether to add Py3.15 support in this PR or not.

I haven't reviewed all changelogs in depth yet:

1. https://github.com/actions/checkout
2. https://github.com/actions/setup-python
3. https://github.com/actions/upload-artifact
4. https://github.com/actions/download-artifact
5. https://github.com/codecov/codecov-action
6. https://github.com/conda-incubator/setup-miniconda
7. https://github.com/mamba-org/setup-micromamba
8. https://github.com/plbstl/first-contribution (not updated)

Should we move from setup-miniconda (in pytest-remote-data.yml) to setup-micromamba (as in pytest.yml).

Seems like yesterday-released pandas 3.10 said no-no to our codebase. I suggest we all have a look at the changelog, as it seems to be a big release https://pandas.pydata.org/docs/whatsnew/v3.1.0.html that deserves big updates through all our codebase.
