🚚(helm) update values for remote environments

I have updated the staging, pre-prod and production environments.

Done:
- Remove silenced security checks, as SECURE_PROXY_SSL_HEADER is set in prod.
- Rename "impress" to "meet"
- Rename "docs" to "meet"
- Remove unused values (webrtc, ingressWS)

I haven't yet received the definitive DNS configuration from Florian or Olivier.
The hosts meet.numerique.gouv.fr and all meet-*.beta.numerique.gouv.fr are
only hypothetical at this point.
