The Platform Mesh resource should only get ready when all helmreleases are ready

[nexus49]

Currently the local setup script waits for a number of helmreleases after the platform-mesh resource is ready.

This should not be the case: When the platform-mesh resource is ready, platform-mesh should be ready to be used.

Add a new subroutine that waits for all helmreleases that platform-mesh operator has created. Possibly this requires labeling of the helmreleases that the platform-mesh-operator-components and platform-mesh-operator-infra-components charts create.

Also think about that this subroutine may need to wait for other resources in the future, eg ArgoCD Applications or similar.
