Add DATABASE_HOST as forwarded env variable

[Amphaal]

https://github.com/calcom/docker/blob/main/scripts/start.sh, would be needed to correctly probe that PostgreSQL instance is running.

Maybe should we include extraEnvVars or something like this to be passed to Deployment pod ?
Or maybe just bind all key/pairs in expected Secret manifest as env variables ?

envFrom:
  - secretRef:
      name: calcom

That's already the case, assuming cal.com keep their .env.example file updated (which looks like they don't).

Will add DATABASE_HOST for future release, and/or check to open the mounting of the secret to any variable as we will have a delta between their update and the chart.

Thanks!
