Opened Up Group Creation

Now anyone can create their own group on Indie Hackers!

@rosiesherry announced it here if you'd like to read more details: https://www.indiehackers.com/post/you-can-now-create-your-own-group-on-indie-hackers-c33e12379b

There are still lots of follow-up features I need to add to groups, so my plan is to come back and revisit them in a few months once we've gotten more time to see how people use them.

In the meantime, I encourage you to create a group for any topic you're interested in, and invite others to join you in discussion.
