[bug#74234] [PATCH rust-team] Add gnome-authenticator

[paul]

Hi Guix,

I am about to send revision 2 the the fourth and last patchest required 
to build GNOME Authenticator in Guix. It adds gnome-authenticator and 
its last dependencies.

With respect to revision 1, these changes were introduced:

- this patches depend on revision 2 of issue #74233
- pango 1.52 is used instead of pango 1.51

This patchset depends on the first, second and third ones available at:

1. https://issues.guix.gnu.org/73956
2. https://issues.guix.gnu.org/74232
3. https://issues.guix.gnu.org/74233

Thank you for your work!

Cheers
