Just as we did in T284740: Donors to newcomers: design an enhanced account creation landing page, we need to create a special account creation page for this recurring donor email. It will be very similar to that previously created landing page.
Graphic: same heart graphic
Header: "Thanks for being a loyal supporter. It’s contributions from readers like you that keep Wikipedia thriving."
Body: "Create your account now to log in and avoid seeing fundraising banners. Once you have an account, you can also learn to edit Wikipedia with small changes that will have a big impact for the rest of the world. We’ll be there to guide you as you start!" (no bullet points with icons like in the previous landing page)
Destination: after account creation, all users go straight to Special:Homepage (geEnabled=1)
