Image: use relative url

Embedding the full URL into the notes is a bit anoying if you want to
change hostname (or e.g. hosting from a local IP). Using the relative
URL should work in all(?) cases afaik.

I would also like to remove that `additionalUrlText` argument, which is
a bit confusing (not sure it works as intended?). It is only used in
file `use-on-image-upload-from-renderer.ts` - and not sure it even is
set to anything
