[IMP] requirements: drop support for py3.7

All major systems (debian stable, ubuntu lts, windows) support py3.8
and all dependencies used by Odoo come with wheels for that version.
Most developers at Odoo SA uses 3.8 already and runbot is using ubuntu
jammy (which comes with py3.10) to test the current 16.0/master.
