[bug#51103] [PATCH core-updates-frozen] news: Notify of Wayland support in GDM

[Josselin Poiret <dev@jpoiret.xyz>]

Hello,

I've written a news entry to inform users of the newly added Wayland support in GDM.
After discussing it in issue 50563, we thought it'd also be a good idea to switch Wayland mode on by default, but I don't know when it would be best to do so.
This news entry contains a warning about that change as well. Also, I've written a warning mechanism (not included here) for people using the default value, which I could also add if needed, before or after the change.

As a side-note, I've put the current commit id, but it'll need to be changed when merging. I don't if there's something/someone that keeps track of everything that needs to be done when merging, so I'm just writing this here.
