anki: allow using wayland on linux

[sbruder]

Description of changes

This makes the native version of Anki use Wayland natively (without xwayland).

This patch had already been applied in #221229, though I think it got lost while converting the package to importCargoLock.
Is that correct @euank, or was it removed for some other reason?

Thanks for catching this!

I didn't mean to lose this, I think I messed up a rebase 😅, and I'm still on X11 so I didn't test wayland after every change.

Thanks again for catching my mistake here!

No problem. Thanks to you for adding the native Anki version (and also figuring out how to make it work with Wayland in the original PR)!
