Short answer, you can't do this.

Wikipedia runs on a different version of MediaWiki, has different extensions, and has different configuration settings values. You can't always copy things from Wikipedia verbatim to Fandom. As such, I don't know if what you are trying to do will work. That said, even if it could, you wouldn't be able to do it as editing of the Mediawiki namespace is restricted to whitelisted messages only. The message you mentioned is not on the current whitelist which is for non-UCP wikis. My understanding is that the current whitelist for UCP wikis is even stricter than that for non-UCP wikis.
