Add nodePublishSecretRef to secret provider class volumes

[nisan-abeywickrama]

Purpose

This pull request enhances the configuration of secret provider classes in several Helm chart deployment templates by introducing support for the nodePublishSecretRef parameter.

Approach

Helm chart deployment improvements:

• Added support for the optional nodePublishSecretRef parameter in the secret volume configuration for the following deployments: adapter-deployment.yaml, common-controller-deployment.yaml, gateway-runtime-deployment.yaml, and ratelimiter-deployment.yaml. This enables referencing a specific Kubernetes secret when mounting secrets with the CSI driver.

Configuration enhancements:

• Introduced the nodePublishSecretRef field under wso2.apk.secretProviderClass in values.yaml, allowing users to configure this value via Helm values.
