github-actions: add max pandas version

    - Add a temporary max pandas version to prevent
      incompatibility issues between different rdkit
      version.
    - The temporary version limit will be removed
      when the latest rdkit version can be installed
      via pip (see this issue for details
      kuelumbus/rdkit-pypi#99)
