Add Corporate Booking Indicator to Confirmation Emails

Currently, corporate bookings can be identified by drilling into a class from the calendar view. Add a visible note or label in the Admin Enrolment confirmation emails (packages/email-templates/src/templates/rto-pilot/system/AdminNewEnrolmentEmail.tsx) to flag when an enrolment is a corporate booking, so staff are notified as soon as the enrolment occurs.
