fix(gatsby-source-drupal): skip jsonapi_schema endpoint (#19879)

The JSON:API Schema module (https://www.drupal.org/project/jsonapi_schema) adds a `describedby` link to resources. This payload doesn't contain a JSON:API document, but information describing the object's schema. It's not a valid source of content.

After debugging, it is the original cause of #19867
