[SPARK-54896] Improve Helm templates to use Spark Operator HA feature easily
### What changes were proposed in this pull request?
Set default configuration on the helm template in order to support high
availability of the operator without requiring specific configuration from the
user
### Why are the changes needed?
Simplify setup of HA, only need to increase the number of replicas
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Run helm template with 1 and more replicas to check that added resources
are well displayed
Deployed on a local kubernetes cluster with replicas set to 3
### Was this patch authored or co-authored using generative AI tooling?
No
Closes #437 from ashangit/nfraison/high-availability.
