  /**
   * expression will be evaluated by CEL to create a [JSON patch](https://jsonpatch.com/). ref: https://github.com/google/cel-spec
   *
   * expression must return an array of JSONPatch values.
   *
   * For example, this CEL expression returns a JSON patch to conditionally modify a value:
   *
   * 	  [
   * 	    JSONPatch{op: "test", path: "/spec/example", value: "Red"},
   * 	    JSONPatch{op: "replace", path: "/spec/example", value: "Green"}
   * 	  ]
   *
   * To define an object for the patch value, use Object types. For example:
   *
   * 	  [
   * 	    JSONPatch{
   * 	      op: "add",
   * 	      path: "/spec/selector",
   * 	      value: Object.spec.selector{matchLabels: {"environment": "test"}}
   * 	    }
   * 	  ]
   *
   * To use strings containing '/' and '~' as JSONPatch path keys, use "jsonpatch.escapeKey". For example:
   *
   * 	  [
   * 	    JSONPatch{
   * 	      op: "add",
   * 	      path: "/metadata/labels/" + jsonpatch.escapeKey("example.com/environment"),
   * 	      value: "test"
   * 	    },
   * 	  ]
   *
   * CEL expressions have access to the types needed to create JSON patches and objects:
   *
   * - 'JSONPatch' - CEL type of JSON Patch operations. JSONPatch has the fields 'op', 'from', 'path' and 'value'.
   *   See [JSON patch](https://jsonpatch.com/) for more details. The 'value' field may be set to any of: string,
   *   integer, array, map or object.  If set, the 'path' and 'from' fields must be set to a
   *   [JSON pointer](https://datatracker.ietf.org/doc/html/rfc6901/) string, where the 'jsonpatch.escapeKey()' CEL
   *   function may be used to escape path keys containing '/' and '~'.
   * - 'Object' - CEL type of the resource object. - 'Object.<fieldName>' - CEL type of object field (such as 'Object.spec') - 'Object.<fieldName1>.<fieldName2>...<fieldNameN>` - CEL type of nested field (such as 'Object.spec.containers')
   *
   * CEL expressions have access to the contents of the API request, organized into CEL variables as well as some other useful variables:
   *
   * - 'object' - The object from the incoming request. The value is null for DELETE requests. - 'oldObject' - The existing object. The value is null for CREATE requests. - 'request' - Attributes of the API request([ref](/pkg/apis/admission/types.go#AdmissionRequest)). - 'params' - Parameter resource referred to by the policy binding being evaluated. Only populated if the policy has a ParamKind. - 'namespaceObject' - The namespace object that the incoming object belongs to. The value is null for cluster-scoped resources. - 'variables' - Map of composited variables, from its name to its lazily evaluated value.
   *   For example, a variable named 'foo' can be accessed as 'variables.foo'.
   * - 'authorizer' - A CEL Authorizer. May be used to perform authorization checks for the principal (user or service account) of the request.
   *   See https://pkg.go.dev/k8s.io/apiserver/pkg/cel/library#Authz
   * - 'authorizer.requestResource' - A CEL ResourceCheck constructed from the 'authorizer' and configured with the
   *   request resource.
   *
   * CEL expressions have access to [Kubernetes CEL function libraries](https://kubernetes.io/docs/reference/using-api/cel/#cel-options-language-features-and-libraries) as well as:
   *
   * - 'jsonpatch.escapeKey' - Performs JSONPatch key escaping. '~' and  '/' are escaped as '~0' and `~1' respectively).
   *
   * Only property names of the form `[a-zA-Z_.-/][a-zA-Z0-9_.-/]*` are accessible. Required.
   * @type {string}
