This is used for LanguageSwitcher feature (generate links for current content in a different language if available).
Will use configured translation_siteaccesses if any. Otherwise will use related siteaccesses (e.g. same repository, same rootLocationId).
Will return null if no translation SiteAccess can be found.
/**
* If "language" parameter is present, will try to get corresponding SiteAccess for translation.
* If found, it will add "siteaccess" parameter to the RouteReference, to trigger SiteAccess switch when generating
