a couple weeks ago, [python-augeas
1.2.0](https://pypi.org/project/python-augeas/#history) was uploaded to
pypi. unfortunately, this broke things for us
the first major change was from
https://github.com/hercules-team/python-augeas/pull/49 where
python-augeas now needs the new OS packages described in the initial
comment there
the second change was from
https://github.com/hercules-team/python-augeas/pull/51 which added a
python interface to augeas functions that weren't introduced until
[augeas
1.13.0](af2aa88ab3/NEWS (L65-L66)).
this isn't ideal, but i don't think it's a big deal for us. augeas
1.13.0 is over three years old and [ubuntu
20.04](https://ubuntu.com/blog/ubuntu-20-04-eol-for-devicesional) and
[debian bullseye](https://www.debian.org/releases/) which have older
versions than that are technically EOL'd
regardless of how we feel about these changes, our tests don't currently
work with an updated version of python-augeas and this PR fixes it. i'm
also tracking https://github.com/certbot/certbot/issues/10282 to update
certbot.eff.org to list the newly required OS packages
