Add Essex schools to Hertfordshire training (#3399)

This adds the Essex schools to the Hertfordshire training organisation
so the team can practice using the service. To simplify the onboarding
configuration I've removed the
`hertfordshire-training-with-sessions.yaml` file, although we can bring
this back later if it has use.
