bump minimum Python version up to 3.9

3.7 will reach EOL in June of 2023, so it doesn't really make too much
sense to forcefully stick with it for much longer - especially since
upgrading gives us a few nice things (walrus, type subscription on
builtins).

3.9 is shipped by Debian 11 (stable), so everything should be good.
