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

…928)

* 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
https://github.com/conda-forge/scikit-hep-testdata-feedstock PR 68 on
2024-11-20, 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')"
