[FIX] doc: api.model no longer accept traditional style call

Since we dropped the old-api style compatibility layer,
some years ago.

This docstring was added to the 13.0 documentation
thanks to odoo/odoo#44838
So it's best not to mention this old-api style
in our latest documentation

closes odoo/odoo#46223
