Remove pagemacro inclusion of image guide in HTML>Element>img

[hamishwillee]

This removes the pagemacro inclusion of the Image guide and reference into HTML > Element > img topic on "supported image types". It further removes tidies up the image guide links to fix up some notes and links. This is part of #3196

The change essentially just creates a smaller list and link to the relevant information.

It is also precursor to work I am going to do for #7744

This was my only concern about the edit. IMO webp is now the format of choice unless you need to use SVG - it has broad support, and in terms of market share is "more than deep enough". That is not quite so true of AVIF. Anyway, decided it was time to start pushing the newer formats.
