Update gtk4 to 4.10.4

[Jeremy Bícha]

Impact
-----
There is a new point release in the stable GTK 4.10 series.

https://gitlab.gnome.org/GNOME/gtk/-/blob/4.10.4/NEWS

The version currently in Ubuntu 23.04 is 4.10.3

Test Case 0
-----------
gtk4 has an extensive build test suite, and failures will fail the build.
gtk4 also has thorough autopkgtests.
Ensure that the build succeeds and that the autopgktests pass.

Test Case 1
-----------
Make sure that opening and saving files from the Firefox and Chromium snaps still work

Test Case 2
-----------
snap install portal-test
snap run portal-test
Verify that the app seems to still work ok

What Could Go Wrong
-------------------
Ubuntu includes xdg-desktop-portal-gnome by default which is used for many snap actions like providing a file chooser. This is critical functionality for our snaps.

The Ubuntu flavors use a different portal backend, most commonly xdg-desktop-portal-gtk which uses GTK3 so it's not affected by this SRU.

Many of the default Ubuntu 23.04 desktop apps use GTK4. A serious enough regression could severely break the Ubuntu Desktop.

gtk4 is included in the GNOME micro release exception.

Hello Jeremy, or anyone else affected,

Accepted gtk4 into lunar-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gtk4/4.10.4+ds-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-lunar to verification-done-lunar. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-lunar. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Ubuntu SRU Bot (ubuntu-sru-bot)]

I completed Test Case 1 with gtk4 4.10.4+ds-0ubuntu1 on Ubuntu 23.04 using both the Firefox and Chromium snaps.

The portal-test snap works as well as before.

All the triggered autopkgtests and build tests have passed.
