stellar/soroban-rpc chart: core cfg needs updated settings

[sreuland]

What version are you using?

latest helm chart for stellar/soroban-rpc

What did you do?

helm install my-rpc stellar/soroban-rpc --set global.image.sorobanRpc.tag=22.1.1 --set sorobanRpc.persistence.enabled=true --set sorobanRpc.persistence.storageClass=default --set sorobanRpc.resources.limits.cpu=1 --set sorobanRpc.resources.limits.memory=2560Mi

What did you expect to see?

• the chart name should reflect the newer product name of stellar-rpc
• the deployed pod for rpc instance should be in running state.

What did you see instead?

crashloop backoff on the pod with error logs indicating the captive core cfg file has deprecated settings:

$ kubectl logs my-rpc-soroban-rpc-0
