No issue - Include all non-ubiquitous image and media types in nav Accept:

See: https://github.com/whatwg/fetch/issues/274#issuecomment-2841053461
Considering the ubiquitous nature of gif, jpg, png, mp4, avi, etc. those
are left out, leaving just jxl, webp, x-matroska (mkv) and webm as
explicitly mentioned supported formats for conneg.

Note: it's not clear where network.http.accept.image is used in practice
because our normal place to use the image override (imgloader) uses
a different pref (image.http.accept).
