When setting `url.host` on a URL object with no port specified (like is the case of default port), the resulting URL's port will not change. Workaround this quirk in the URL standard by explicitely setting port for the http and https protocols. Extracted the logic to a function for the purpose of testing. Initially I wanted to have the function in utils.js, but it turns out esbuild can not treeshake the unused functions which would result in the webcomponents chunk having all 2kB utils.js inlined, so it seemed not worth. Fixes: https://github.com/go-gitea/gitea/issues/29084 (cherry picked from commit b6bf8041d8e8ee845728687b1f358f1d482afff2)
