Should be JUPYTERHUB_CRYPT_KEY

Should be JUPYTERHUB_CRYPT_KEY instead of JUPYTERHUB_CRYPTO_KEY

@elgalu Woooo this caused me confusion before but I never grasped the issue clearly.

Overview

1. values.yaml contains the auth.state.cryptoKey entry
2. schema.yaml validates this entry and has misleading documentation written about it
3. secret.yaml (named: hub-secret) saves this value in it as auth.state.crypto-key
4. deployment.yaml (named: hub) reads the secret value and provides it to the hub pod as an environment variable named JUPYTERHUB_CRYPT_KEY
5. JupyterHub utilize this key without additional configuration.

Conclusion

I think the statement in schema.yaml should be updated in the way you suggest! I'd also want to make it clear that the value provided in values.yaml will be used to set the environment variable and not the other way around. I added a commit to do this, does it look good to you @elgalu ?
