community/deja-dup: Deja Dup's Google support will break in September 2022 for versions < 43.3

Hello! I'm the usptream maintainer of Deja Dup. I was recently made aware that Google will be removing an oauth workflow that Deja Dup uses in September.

This means that any new authentications for users trying to connect Deja Dup to their Google account will fail after that date (existing users that have already authenticated themselves will continue to work).

Here's a wiki page for more information about the issue, including backported patches for older versions: https://wiki.gnome.org/Apps/DejaDup/GoogleAuthChange2022
