Last release from 2019, hasn't migrated to python3.

Claims to support python3, but I'm seeing it use implicit relative
imports and it also has not adapted to python3.8 gettext API changes.
Removed for working only with python2.
Still actively developed and yet stuck on python2. Also marked as
vulnerable and their issue tracker contains yet another security issue
reported in 2021/10 that the upstream hasn't acknowledged yet.
Mind blown.
Closes: #135543, #97274, #97275
The package is unmaintained and uses python2. There are newer upstream
versions, but upgrading the package requires some dedication, which only
a maintainer should need to provide.
A new symlink is required to fix the following error:

The GPU acceleration still fails (not sure if it worked before) but at least
"signal-desktop --enable-features=UseOzonePlatform --ozone-platform=wayland"
launches again (without "--disable-gpu"):

(After three GPU process crashes Chromium should automatically fall back
to software rendering.)
Fix#155050 (it only fixes the crashes though, not the underlying
issue, but that's likely all we can do for the moment as other Linux
distributions are affected as well; Ozone/Wayland is just not stable yet)
