Conflicting information on screenshot aspect ratio recommendation

[sidt4]

From https://gitlab.gnome.org/GNOME/gnome-software/-/merge_requests/2109

I think there is conflicting information in the following links.

https://www.freedesktop.org/software/appstream/docs/sect-Metadata-Application.html#tag-dapp-screenshots

• All screenshots should have a 16:9 aspect ratio, and should have a width that is no smaller than 620px

https://www.freedesktop.org/software/appstream/docs/chap-Quickstart.html#qsr-app-screenshots-info

• Use an aspect ratio that works for the applications's UI, use 16:9 as long as that is sensible.

I feel screenshot aspect ratio is highly app specific, and the later paragraph makes more sense than the former.

Also, it would probably be more reasonable if AppStream could recommend a aspect ratio range ( e.g. 14:9 to 16:9 etc)
