Check dependency on pytz

[psaiz]

After the the release 2.2.0 of invenio-i18n, we get the following error:

104.3 invenio-i18n 2.2.0 requires pytz<2024.2, but you'll have pytz 2024.2 which is incompatible.
104.6 WARNING: You are using pip version 20.2.4; however, version 24.3.1 is available.
104.6 You should consider upgrading via the '/usr/bin/python3 -m pip install --upgrade pip' command.
105.9 invenio-i18n 2.2.0 has requirement pytz<2024.2, but you have pytz 2024.2.

Note that opendata didn't require directly pytz. This has been temporarily fixed by
c2e6696

It would be better to identify the package that requires the old version of pytz, fix it there, and remove the direct dependency from opendata
