Update Preference Center Landing page

[data-sync-user]

This project is part of the effort to deprecate cTms as well as partition subscription preference centers between MoFo and MoCo.

MoFo (CRM team) will remove options for any active Mozilla Foundation list (Mozilla News, Mozilla Festival, Insights, Common Voice, TAFTI) via +Basket admin interface+. 

1. Request for MoCo to add language to Preference Center:

“Newsletter subscriptions for +Mozilla Foundation+ are now managed separately. To unsubscribe, from a Mozilla Foundation newsletter click here <Link to Unsubscribe Page>. If you aren’t already subscribed and would like to stay updated, click here <Link to Subscription Page>.

Delivered no later than 10/15 but launch date is being finalized by MoFo.

Request Google Doc from MoFo here: https://docs.google.com/document/d/1vdN1s2BeJEXztcnxCr79KXhIxDk3YTiSR-nomSNY4Mo/edit?tab=t.0
