Reclaim some storage space in the middle of the CI job that builds and
installs Dangerzone in Fedora. The reason is that previously, we
encountered an issues with CI runners running out of space.
Add some Fedora CI jobs that build RPMs, install them in an end-user
environment, and make a simple conversion and GUI import check. These
are basically smoke tests for Fedora, similar to the ones we have for
Debian.
Ensure that when the container image is installing pymupdf (unavailable
in the repos) with verified hashes. To do so, it has the pymupdf
dependency declared in a "container" group in `pyproject.toml`, which
then gets exported into a requirements.txt, which is then used for
hash-verification when building the container.
Because this required modifying the container image build scripts, they
were all merged to avoid duplicate code. This was an overdue change
anyways.
Python 3.10.12 fixes some CVEs for which Dangerzone does not appear to be
affected, however its binaries are not made available by the python
foundation. Moving to 3.11 should be trivial since this was already
deployed in Fedora 37+.
The Ubuntu 23.04 docker image includes a user by default (ubuntu) which
overtakes the 1000 uid and so our user becomes 1001 which makes the user
directory unwritable. The solution as suggested in [1] was to remove
that user.

Update our GitHub Actions workflow with the following tests:
1. Build a .deb for Dangerzone on Debian Bookworm.
2. Install this .deb on every Debian-based platform that we support.
3. Test that the installed version runs successfully.
This way, we can be sure that .deb that we create on a single Debian
version (here we choose Debian Bookworm) works on all platforms.

Adds tests for macOS and Windows with the dummy converter. Tests won't
actually perform the conversion. But it should be enough for us to test
the remainder of the codebase.
Fixes#229
