My understanding of this policy is that you *can* download *data*, but
can't download and run executable code:
https://sources.debian.org/src/autopkgtest/5.49/doc/README.package-tests.rst/#L569
pandas has network-using tests and they're passing.
Hence, the Forbidden in this particular test is probably coming from the
data source, not Debian. Hence, substituting a different online data
source (if a suitable one can be found) should work.
