GET /webform_rest/{webform_id}/fields should use cache

Pinesh Kumar → made their first commit to this issue’s fork.

To improve the performance of the /webform_rest/{webform_id}/fields endpoint by enabling caching, ModifiedResourceResponse to ResourceResponse. The ModifiedResourceResponse does not support caching, which results in a no-cache directive being set on the HTTP headers, leading to poor performance. The patch below modifies the response to use ResourceResponse, which supports caching and should significantly improve response times.

Cache metadata may be required. Have a read through some previous issues about this: https://www.drupal.org/project/issues/webform_rest?text=ResourceResponse... →
