Description from https://phabricator.wikimedia.org/T309874 which is a duplicate.

There are two emails sent in the selfregistration:

• one to verify email
• one to reset password

We'd like to change the copy of both emails as well as add username placeholder.

2 issues:

• Looks like Cognito use the same template for both verification and reset
• username can’t be added to the email

This second point was our (temporary?) solution for this ticket https://phabricator.wikimedia.org/T309015
