fix(test): dont install AtomDevtools in test envs (#6480)

**Problem:**
Today we get a lot of long warnings in the test logs about AtomDevtools.

**Fix:**
Don't install AtomDevtools in test environments, since they are only
relevant for browser debugging.

**Manual Tests:**
I hereby swear that:

- [X] I opened a hydrogen project and it loaded
- [X] I could navigate to various routes in Play mode
