helm install --wait does not work for openfga chart

[tamalsaha]

The migrate hook never runs because the openfga pods wait for the migrate job to complete when --wait flag is used. Here is a similar issue: fluxcd/flux2#1085 (comment)

I think one way to solve this will be:

• Don't use hook to run the migrate job.
• Increase the timeout and backoffLimit of the migrate job so it waits and retries until the db pods are ready.

I have done this in my fork and it works. Let me know if openfga interested in a pr.
