FIX: Replace minimum required Python for scikit-hep-testdata v0.5.0.

[matthewfeickert]

• https://github.com/conda-forge/scikit-hep-testdata-feedstock has broken metadata for package scikit-hep-testdata-0.5.0-pyhd8ed1ab_0.conda. (https://anaconda.org/conda-forge/scikit-hep-testdata/files?version=0.5.0) The package has a 'run' requirement of python >=3.8 but scikit-hep-testdata v0.5.0 dropped 3.8 support and is Python 3.9+. This was fixed in MNT: Use noarch python {{ python_min }} variable scikit-hep-testdata-feedstock#68, so use 1732172400000 (2024-11-21 in human readable metadata) as the cutoff timestamp.

$ python -c "import datetime; print(f'{datetime.datetime(2024,11,21).timestamp():.0f}000')"
1732172400000

• Required for uproot-browser v0.7.2 uproot-browser-feedstock#13

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.
