PROD-31232: Implement "group create" event for the EDA

[nkoporec]

Problem (for internal)

Currently we don't have an EDA event that fires when a group is created.

Solution (for internal)

Add the new event

Payload:

@nkoporec I have rebased with main (which is fixed now), but I still see that PHPStan and PHPCS still failing.
Could you check it, please?
