ImageList images cannot be WEBP or AVIF

[NicolasDerumigny]

What needs to be fixed

Add webp and avif (or the media configured by the user in the global parameters) to here.

Why this should be fixed

Images cannot be chosen in WEBP or AVIF format with this field.

How would you fix it

Add $|\.webp$|\.avif to the string in libraries/src/Form/Field/ImagelistField.php

Side Effects expected

None

Thanks for your suggestion! As you already know how to resolve your request, would you like to make yourself a a PR for that? A more flexible solution could be replacing the hard coded list by a user defined list of allowed types.
