Right now we only compare the hostname from a submodule with the prefixURL it is viewed from to check if the submodule is hosted on the same Gitea instance. This adds an additional check to compare it against SSH_DOMAIN as well since the same Gitea instance might have a different hostname for SSH and if the submodule uses that hostname we should also detect that and link to the proper DOMAIN value.
Fixes #12747, #9756
Use combination of url.Parse and regex to parse refURL rather than by
hand with indexes & attempt to check if refURL is from same instance and
adjust output to match.
Also now return empty string instead of our original
guess at URL if we are unable to parse it.
Fixes #1526
