Adjust a e2e-test that made a bad assumption.

Installing py3-pandas does not guarantee you a /usr/bin/python3.
This is fallout of our choice to make pythons co-installable.
More info on this wolfi-dev/os#26818

Adding 'python-3' will get you _some_ python3, but currently
not strictly guaranteed to be the same python3 that the pandas
install was using.

Another option would be to just drop the test here and in
e2e-tests/py3-pandas-nopkg-test.yaml.
