[FIX] packaging: set fedora 36 as base for rpm

Also, as the rpm is not built from the deprecated bdist_rpm anymore, it's
time to remove useless requires from the `setup.cfg` file.

On the other hand, the soft requirements in the `setup.py` are now
synchronized with the hard requirements.

closes odoo/odoo#102849
