Bookworm Gnome lacks wallpaper withing lightdm

Created image with gnome. Wallpaper worked for me. Hence closing.

I build Bookworm Gnome vendor for OPi5+ and GDM3 is enabled by default. It is the regular color of gdm3 without wallpaper at login.
But lightdm was also installed by default… I think that should be removed for gnome.

Thank you Nico! We think its O.K., but someone needs to verify.

I think we switched to GDM3 for Gnome desktops. I can check tomorrow if I don’t forget.

Test if this is still needed.
