x/pkgsite: source file links for unknown hosts should not link to self

[runxiyu]

What is the URL of the page with the issue?

https://pkg.go.dev/go.lindenii.runxiyu.org/forge@v0.1.41/forged/cmd/forge

What is your user agent?

Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0

Screenshot

What did you do?

I host some projects on an uncommon software forge.

Tree links are like /tree/dir/dir/file appended to the repo root.

What did you see happen?

The View all Source files and main.go anchors refer back to the same page on pkgsite.

What did you expect to see?

Both links are removed or greyed out to indicate that pkgsite does not know the URL scheme of the forge.

@gabyhelp I believe that this should be considered a bug rather than a feature request.
