Fixes #1155

hmm... all the remaining issues with the CI seem to be out of this MR's scope

Thanks for looking at it too! I've had 0 free time for software lately :(

The failures look to be the same as in https://github.com/getting-things-gnome/gtg/actions/runs/12245946645/job/34160890047, which were fixed in 95e33bc. So I think if you just rebase this onto latest master, the tests should work.

If that's the case, and if we've tested that the changes result in a working flatpak, then LGTM.

One day we'll talk about the fact that we're pinning requirements to exact versions, but that doesn't have to be today :)

I rebased this on top of master and tested the flatpak GHA (https://github.com/SqAtx/gtg/actions/runs/12978178115), but it doesn't run:

$ flatpak run org.gnome.GTG.Devel

I'll mark the MR as a draft, because I really don't know what's causing this

It seems a newline (\n) is missing from the end of the python3-requirements.json file.

Fixing build-aux/python3-requirements.json

[TheEvilSkeleton]

Oh yeah, I'm aware of the pre-commit failure. It was more-so the lxml module not being found

[TheEvilSkeleton]

I managed to fix it and have it working locally. Can anybody test it just for sure?

It works for me too. :)

[SqAtx]

I tried to validate the changes using GHA but ran into #1184 :) So we'll fix that one separately.

I built the flatpak locally and it worked, so LGTM!

Note that this fixes #1179 as well.
