[Feedback] Add join date here aswell

When we open a post and tap on the groundbreaker badge it doesn’t show the join date. Only on profiles itself is it displayed.

(Screenshot 2 shows example of what I mean. I added the join date there)

This is just a minor ask, so I hope it can be added at some point in the future.

- Also would be nice if it can be added for people without groundbreaker badge.

Thanks!
