Update gdm3 to 44.0

[Jeremy Bícha]

Impact
-----
Ubuntu 23.04 is shipping GNOME 44, but one key component landed late.
This includes several fixes to the udev rules (used to determine whether Wayland is available and default) and other bugfixes. GDM 44 looks better for Ubuntu 23.04 users than 43.

https://gitlab.gnome.org/GNOME/gdm/-/blob/44.0/NEWS

gdm is only included by default in the Ubuntu and Edubuntu desktop flavors. (Edubuntu 23.04 is basically Ubuntu Desktop plus educational apps).

Testing Done
------------
I have been running gdm 44 on my computer since Monday, March 27 without seeing any new issues. I have restarted my system multiple times since then.

Why Wasn't this done sooner
---------------------------
gdm 44 was released during my spring break week.
I returned to work the Monday of Beta Freeze. It seemed unwise to push this update through at the last minute before Beta in case there were any issues.

gdm upstream has a bad habit of not doing pre-releases but just landing the stable release and even that might be late.

This bug was fixed in the package gdm3 - 44.0-1ubuntu1
