Bug#1033274: gnome-session: recommends xdg-desktop-portal-gnome and not depends

[Pablo Mazzini]

Package: gnome-session
Severity: normal

gnome-session can work properly without xdg-desktop-portal-gnome.

As per the policy:
Depends: This declares an absolute dependency.
Recommends: This declares a strong, but not absolute, dependency.

Please recommend xdg-desktop-portal-gnome.

The gnome-core meta package already provides this dependency and it may
be appropriate there.
