Charm doesn't install for Focal due to lack of /usr/bin/python

[James Simpson]

Just tried a deploy on Focal:
2022-08-04 08:14:12 WARNING unit.ubuntu-mirror/0.install logger.go:60 /var/lib/juju/agents/unit-ubuntu-mirror-0/charm/hooks/install: /var/lib/juju/agents/unit-ubuntu-mirror-0/charm/hooks/install.real: /usr/bin/python: bad interpreter: No such file or directory

2022-08-04 08:14:13 INFO juju.worker.uniter resolver.go:144 awaiting error resolution for "install" hook

Installing "python-is-python2" and "juju resolve"ing works as a workaround.

It may be worth tackling this by implementing LP:1890205 and migrating to Python3.

Note that python-is-python2 is gone in jammy
