Update copy in account recovery settings global alert

📖 What does this MR do?

Related to #297366 (closed)

Updates the copy in the account recovery settings alert let the user know they should ensure their 2FA settings are up to date. Previously there was some confusion about what settings should be checked. This MR also takes the opportunity to refactor this alert to use the app/views/shared/_global_alert.html.haml HAML partial which helps improve consistency of global alerts.
