gajim: update to 2.4.0.

[lissine0]

• python3-omemo-dr: update to 1.0.1.

• python3-nbxmpp: update to 6.4.0.

• New package: python3-truststore-0.10.4: this is a new dependency of gajim-2.4.0. I based the template on this part of a stale PR.

• gajim: update to 2.4.0.

New gajim dependencies since v2.2.0: libadwaita, python3-h2, python3-httpx, python3-socksio, python3-truststore (I kept the dependency list ordered alphabetically, so the git diff might not be obvious)

Note that python3-h2 and python3-socksio are optional dependencies of the python3-httpx library that are required by gajim.

Tested on x86_64-glibc, works

Also tested on x86_64-glibc, and it works. I had to manually install python3-nbxmpp.

Edit - 2.4.0 broke my OMEMO encrypted MUC, but I'm pretty sure it's a Gajim issue (https://dev.gajim.org/gajim/gajim/-/issues/12544)

[chilledfrogs]

Bumped versions in my local build to 2.4.1 and python3-nbxmpp to 7.0.0, works well on my machine

I updated the PR to gajim-2.4.1

@chilledfrogs you should install the new dependencies (gst-plugins-bad1, gst-plugins-good1 and gst-plugins-rs1) if you want animated images (e.g. GIFs) to show a preview and to be playable in the chat.

Tested 2.4.1 on new python, works so far
