[ETP-811] allow the count to update even if not public

[ETP-811]

🗒️ Description

Fixes the issues where while using tribe_tickets_attendees shortcode, 0 attendees always shows up. Did so by matching how the Block version was handling the variables, then matched the template variable being passed because it wasn't matching.

I also removed the public call to the Attendee List query as it only removes all the avatars from showing. The user being able to hide their avatar when purchasing a ticket still functions properly.
