     * Types, fields, arguments, and enum values are all reordered.
     *
     * `typesOnly` sorts only the type list. Field and enum value order stay as loaded.
     *
     * @example
     * Given:
     * ```graphql
     * enum DayOfWeek { SUNDAY MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY SATURDAY }
     * type Query { d: String z: String a: String day: DayOfWeek }
     * ```
     *
     * `sort: true`:
     * ```graphql
     * enum DayOfWeek { FRIDAY MONDAY SATURDAY SUNDAY THURSDAY TUESDAY WEDNESDAY }
     * type Query { a: String d: String day: DayOfWeek z: String }
     * ```

     * `sort: true, sortMode: 'typesOnly'`:
     * ```graphql
     * enum DayOfWeek { SUNDAY MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY SATURDAY }
     * type Query { d: String z: String a: String day: DayOfWeek }
     * ```
     *
     * `sort: false` ignores `sortMode`.
