[Pkg-utopia-maintainers] Bug#1091414: network-manager: Update watch file

[Jeremy Bícha]

Source: network-manager
Version: 1.50.0-1

network-manager's watch file currently points to download.gnome.org

This month, GNOME has switched to the GNOME Release Service which
generally restricts access to publish tarballs on download.gnome.org
to projects hosted in either the GNOME or Incubator groups on GNOME
Gitlab.

There could be exceptions but since NetworkManager is not even hosted
on GNOME Gitlab (it uses Freedesktop Gitlab instead!), I would expect
that future tarballs would be served from Freedesktop's website
instead.

If you don't need the pre-built HTML docs and manpages (which maybe
Debian doesn't want anyone to ensure we can rebuild from source), then
you may want to use the automatically tagged tarballs. Otherwise,
there are released versions available at
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/releases
including this week's new 1.50.1 release.

Thank you,
Jeremy Bícha
