For historical reasons Gitea manually alters the urlPrefix and replaces a whitespace with a +. This Works for URLs, but we're also passing urlPrefix to git calls and adding the + is breaking the tree path. Goldmark will automatically convert a white space to the proper %20, so we should leave the string as is which lets us pass it to git unmodified and then let Goldmark fix it. Also fixed separate bug in URLJoin I noticed while testing where it will silently discard sections of a path that have # in them (possibly others). We should just escape it first. Fixes 10156
