chore: swap deployEnv to opt in when environment already exists (#5262)

The new logic with no flags is:
1. Check whether workload is uninitialized. If so, prompt for workload init. 
2. Check whether environment is uninitialized. If so, prompt for env init, then proceed directly to env deploy.
3. Deploy workload. 

Now, there is no extra prompt for environment deployment at any time. The behavior is purely opt-in, which actually I think makes more sense.
