Mesh - Need full schema for resource `Dataplane`

The resource definition/schema for `Dataplane` is not expanded:
https://developer.konghq.com/mesh/data-plane-proxy/#schema
Only level-1 attributes are shown.

The old website has the full spec: https://kuma.io/docs/2.11.x/production/dp-config/dpp/#definitions

Start with the Dataplane schema section on the current developer.konghq.com page and compare it with the full definitions in the linked Kuma 2.11.x documentation. Update the current page so the complete Dataplane schema, rather than only level-1 attributes, is shown; verify that the expanded output matches the old full specification.
