fix(@angular/ssr): redirect to locale pathname instead of full URL

Browse Source 
When redirecting to the preferred locale, the previous implementation used the full URL for the 302 redirect to i18n subpaths based on the user's preferred locale. This update ensures that the redirect now uses the locale-specific pathname instead of the full URL.

Closes #29514
