Still needs a version bump

We can automate bump version, in my entreprise we automate bump version with label bump:minor, bump:major, bump;patch. is more easier and reduce error to bump version.

You need to update the schema to get CI passing https://github.com/apache/superset/blob/7f918a4ec0e162be13bf3fc0e2f15aaaa5450cec/helm/superset/values.schema.json#L2

I've got also one more question. Is not liveness/readiness probe also needed for rest Superset's elements (worker and celerybeat)?

we can do this step by step, the PR is already open for several weeks.

For the workers, do we have a status endpoint or a command to check the functioning? same for celery
