"hen egg" problem when used with helm deploy

[lachnerd]

if you deploy this chart with "helm --wait" then it never gets finished, cause the openfga init container is waiting for the migrate-job.
The migrate-job won't start until the helm deplyment is in postinstall/postupgrade so it runs till timeout and openfga pod never gets started.

Also it's pretty weird to use the same groundnuty/k8s-wait-for image in two different versions inside one chart.

@lachnerd feel free to contribute the improvements 😉 !

This issue currently prevents the use of this chart with helmfile if using wait.
