 * operation on a "raw" field. The expectation is to have the return value be as close to the
 * Sanity document as possible. Thus, when we've resolved the node, we want to remap the raw
 * fields to be named as the original field name. `_rawSections` becomes `sections`. Since the
 * value is fetched from the "raw" variant, the references inside it do not have their IDs
 * rewired to their Gatsby equivalents.
