chore: Add compatibility configuration for konnect.runtimeGroupID

[tao12345666333]

What this PR does / why we need it:

konnect.runtimeGroupID is still used as the configuration guide in Konnect. After communicating with team-konnect, we believe that directly replacing konnect.runtimeGroupID with konnect.controlPlaneID may cause disruptive changes. Therefore, it is necessary to add compatibility configurations in Charts to avoid disrupting user deployments.
