Update TrustyAI manifests to allow parameterized images

[RobGeada]

• Allows for the specification of TrustyAI-service images via an optional parameter in the trustyai-service kfdef, if desired. If no image values are passed, the default quay.io/trustyai/trustyai-service:latest is used.

Description

This is now possible:

  - kustomizeConfig:
      repoRef:
        name: manifests
        path: trustyai-service-operator
      parameters:
         - name: trustyaiServiceImageName
           value: NEW_IMAGE_NAME
        - name: trustyaiServiceImageTag
          value: NEW_IMAGE_TAG
    name: trustyai-service-operator
