The text in the image is "Drop your details below and we'll get started with your migration to WordPress.com.", but your text also looks good. Have we decided to go with this one instead?

I'm pretty sure the designs are stale, because the "Current" screenshot in the post had stale text as well - p9Jlb4-ee4-p2

You're right, I noticed that too. But just to make sure, I also checked Figma (F8foKv974Gc5dTHSh0i0Wo-fi-396_7998). But it's a small issue and we're making frequent updates here. So I'll just go ahead and approve.
