/**
 * Returns a query document which adds a single query operation that only
 * spreads the target fragment inside of it.
 *
 * So for example a document of:
 *
 * ```graphql
 * fragment foo on Foo { a b c }
 * ```
 *
 * Turns into:
 *
 * ```graphql
 * { ...foo }
 *
 * fragment foo on Foo { a b c }
 * ```
 *
 * The target fragment will either be the only fragment in the document, or a
 * fragment specified by the provided `fragmentName`. If there is more than one
 * fragment, but a `fragmentName` was not defined then an error will be thrown.
