community/deja-dup: upgrade to 43.4

https://gitlab.gnome.org/World/deja-dup/-/blob/43.4/NEWS.md

Warn about delayed backups due to power saver mode, if it's been over a day since we were supposed to back up

Improve support for mobile screen sizes

Add some in-preferences help explaining some of the always-ignored folders

Bump default volume size from 25/50MB to 200MB, to keep fewer files around and improve network throughput

Minor fixes to our experimental restic support (make sure to unlock the repo and warn if some files could not be read when backing up)

Update Brazilian Portuguese, Chinese (China), French, German, Hebrew, Occitan, Persian, Polish, Portuguese, Russian, Swedish, and Ukrainian translations
