Remove customize homepage banner
What does this MR do and why?
This banner was introduced as an experiment and made part of a product. But now we should remove this banner as it works against our long-term work: gitlab-org/growth/team-tasks#187 (comment 763642305)
How to set up and validate locally
- Login as new user. Make sure there is no banner
