Resource in the option of message is not included in path template

[xiaozhenliu-gg5]

For irm API, annotation resource is listed in gapic-yaml, and defined in incidents.proto:

  - name_pattern: projects/{project}/incidents/{incident}/annotations/{annotation}
    entity_name: annotation

message Annotation {
  option (google.api.resource) = {
    type: "irm.googleapis.com/Annotation"
    pattern: "projects/{project}/incidents/{incident}/annotations/{annotation}"
  };
...
}

but we don't catch it as a path_template, now we are just looking for the resource_reference in the field of message:

const resourceReference = fieldDescriptor.options?.['.google.api.resourceReference']

while the option of message itself should be included as well, which is in messagesMap[property].options.['.google.api.resource']
