Add Site Group to Approve Account Request Emails

I'd like to add the site group of a user to the Approve Account Request Emails.

Currently, there's no tag for adding the site group.

We let users choose a site group when they sign up. We would like the Approver to see the site group alongside the user's other entered information when they are approving a user. This way, the approver can check that the user chose an appropriate site group before approving them.
