ci: bump trivy-action workflow

[krishnaGajabi]

Why is this PR required? What issue does it fix?

Currently, the Helm charts do not provide global variables for configuring common parameters such as the image registry, image pull secrets, image pull policy, and analytics settings.

When deploying the OpenEBS Helm charts, users often need to override these values across multiple subcharts and components. This makes it difficult to locate and configure all the required fields consistently. Providing global variables simplifies configuration and improves the user experience.

What does this PR do?

This PR introduces the following global configuration variables:

global:
  # Global override for container image registry.
  imageRegistry: ""
  # - secret
  imagePullSecrets: []
  # Global overide for image pull policy
  imagePullPolicy: ""
  analytics:
    # Global overide for analytics
    enabled:

These variables allow users to configure common settings in a single place, which will then be applied across the chart components.

Does this PR require any upgrade changes?

No.

Verification

The changes were verified using the following scenarios:

Rendered the templates using helm template to confirm correct value substitution.

Deployed the chart on a Kubernetes cluster with 3 worker nodes (kubeadm-based setup).

Verified that the global values are rendered and applied correctly across the components.
