This task is about showing a short introduction message in the mentor module to newcomers letting them know what a mentor is and why they have one for Wikipedia.
Redline versions are in the Growth Zeplin board
This adds a little banner to the top of the mentorship module explaining mentorship. The banner has a "X" to dismiss it, at which point it is permanently dismissed. It reads: "All newcomer are assigned an experienced editor to answer questions about editing."
Note that on mobile, the mentorship preview card will contain the message until the 'banner' has been dismissed in the module.
