Find all references to the `container.tar.gz` file, and replace them
with references to `container.tar`. Moreover, remove the `--no-save`
argument of `build-image.py` since we now always save the image.
Finally, fix some stale references to Poetry, which are not necessary
anymore.
Drop Ubuntu 20.04 (Focal) support, because it's nearing its end-of-life
date. By doing so, we can remove several workarounds and notices we had
in place for this version, and most importantly, remove the pin to our
vendored PyMuPDF package.

Move container-only build context (currently just the entrypoint script)
from `dangerzone/gvisor_wrapper` to `dangerzone/container_helpers`.
Update the rest of the scripts to use this location as well.
Now that our image tarball is not tagged as 'latest', we must first grab
the image tag first, and then refer to it. We can grab the tag either
from `share/image-id.txt` (if available) or with:
docker load dangerzone.rocks/dangerzone --format {{ .Tag }}
Build Dangerzone images and tag them with a unique ID that stems from
the Git reop. Note that using tags as image IDs instead of regular image
IDs breaks the current Dangerzone expectations, but this will be
addressed in subsequent commits.
Previously, the actions were duplicated, due to the fact when developing
we often create feature branches and open pull requests.
This new setup requires us to open pull requests to trigger the CI.
GitHub actions somehow managed to downgrade our runners from Ubuntu
24.04 to Ubuntu 22.04, even though we use `ubuntu-latest`. Make the
Ubuntu 24.04 requirement more explicit, until GitHub migrates fully to
this version for the `ubuntu-latest` tag.
Fixes#957
As part of this change, the dev (build) and end-user test images names
changed from `dangerzone.rocks/*` to `ghcr.io`.
A new `--sync` option is provided in the `env.py` command, in order to
retrieve the images from the registry, or build and upload otherwise.
