Fix issue in ServingRuntime ConfigMap enablement

[lucferbux]

Description

Fix issue with the deployment of the servingruntimes-config ConfigMap
Fix https://issues.redhat.com/browse/RHODS-6779

How Has This Been Tested?

• Update from a previous version without a “default-config” key -> A “default-config” key must be created with the latest version in odh-deployer ✅
• Update from a previous version with a “default-config” key -> We should revert back the default-config, an override-config is targeted for custom deployments ✅
• Update from a previous version with no configmap -> We need to create the configmap with a default version ✅
