bug#40292: Inaccurate hint (upgrade both `epiphany` and `gtk+`) when gtk+ is not installed

[Alexandros Theodotou]

Hi,

I was getting the following when trying to upgrade with `guix upgrade`
and I couldn't upgrade. I did remove gtk+ but the message still
mentions gtk+. I only had gtk+:doc installed at this point so the error
message should mention that, otherwise it's confusing.


```

guix package: warning: package 'zrythm-git' no longer exists
guix package: warning: Consider running 'guix pull' followed by
'guix package -u' to get up-to-date packages and security updates.
