migrate pocket hits signup (Fixes #10756)

[nathan-barrett]

Description

This is just the Front end for the pocket hits sign up page - not sure how we will end up handling the email validation and form submission. Since the FE is finished, I wanted to get some eyes on it so that when the back end is finished it could be merged.

@nathan-barrett Is this page still current in terms of Pocket mode, or can we close this PR, please?

[nathan-barrett]

@stevejalim I wasn't sure what to do here actually - since we were waiting on the pocket hits being moved to basket (still not sure on the status) So i waited on publishing this PR - but not sure the best route to take here. cc: @slightlyoffbeat Any idea on the status of the pocket hits mailing list to use basket?

[slightlyoffbeat]

Pocket hits will not be moving to basket. Pocket team will be using Braze: https://www.braze.com/docs

We should pause on this page and re-gather the new requirements from the pocket front end team and see how to best move forward.
