Incorrect blog newsletter signup id on translated pages

[data-sync-user]

Bug reported by Shing on Slack

{quote}tldr; I think it's a bug not a feature.I signed tested signup on this page (spanish version) to a newsletter and finished the double opt in process, and it looks like I'm now signed up for the F&A list and not the mozilla main list. https://foundation.mozilla.org/es/blog/how-to-tell-chat-gpt-generated-text/ When I do it in english on the same blogpost, I get signed up for mozilla news which is expected behavior.{quote}
