Installation documenation has non-working default values

[chrisbal-b]

Hi,
I'm trying to deploy landscaper based on https://github.com/openmcp-project/landscaper/blob/main/docs/installation/install-landscaper-controller.md#option-2-installation-via-helm

I have noticed that the migration from Gardener to openmcp-project seems to be incomplete. The documentation and the helm charts are still referring in parts to the old registry (europe-docker.pkg.dev/sap-gcp-cp-k8s-stable-hub/landscaper/github.com/gardener/landscaper/images).

E.g. when installing
helm install -n ls-system landscaper ./charts/landscaper
it still uses the old registry here. On the filp side, it uses the new version scheme adapted after the gardener->openmcp-project versioning scheme (here).
This results in trying to find the new image (v.1.0.6) in the old registry, where images were labeled v.0.xxx.0.
