[Bug 2037326] [NEW] [SRU] Alacarte requires python3-cairo, however it is not listed as a dependency

[Launchpad Bug Tracker]

[ Impact ]

 * Alacarte fails to start if python3-cairo is not already installed in
the system

[ Test Plan ]

 * A simple test plan of the package.
   - confirm that python3-cairo is not already installed in the system
   - install alacarte.
   - confirm that it has also installed python3-cairo.
   - execute alacarte and confirm that the gui shows

[ Where problems could occur ]

The change is already in Debian now and is not modifying any source code of the package.
It is only adding python3-cairo to the runtime dependency list.
So, it should not change the behaviour and has little chance of regressing the user behaviour.

[ Other Info ]

As mentioned in the Debian bug, the dependency on python3-cairo was
introduced from v3.44.2 in Debian. But this was originally introduced by
upstream at v3.42.0 as can be seen at
https://gitlab.gnome.org/GNOME/alacarte/-/blob/3.42.0/Alacarte/ItemEditor.py#L19

So, the problem exists in Jammy (3.44.1-1), Lunar (3.44.2-1) and Mantic (3.50.0-1).
Debian has fixed the issue in 3.50.0-2 which is now in Noble.
