feat: switch to health checks for init package waits

[AustinAbro321]

Description

By using health checks we can ensure that resources are fully reconciled before continuing to the next component. This is especially important for the registry component. Since the registry is a re-deploy of the same helm chart as the seed-registry the deployment is already available with extra pods and the current wait condition passes immediately.

Closing this as #3043 is going to add this functionality to all deployments by default
