The CREATE TEAM MEMBERSHIP endpoint requires the email of the user to be added to the team. If the user does not exist in the project, a new user is created with the specified email and added to the team.
The first version of the test creates 5 users, and then adds them to the newly created team. This process is more streamlined now, by using the CREATE TEAM MEMBERSHIPS behaviour to create a user on the go and create a membership for them immediately after.
I also change the way I add user IDs to the array, by using the shorthand notation instead of the `array_push` function.
