+ * Returns a string representation of the given `GraphQLSchema` in SDL format.

+ * **Note**: This function will *not* print directives in the SDL format.
+ * If your intent is to print a schema with directives, use [`printSchemaWithDirectives`](https://the-guild.dev/graphql/tools/docs/api/modules/utils_src#printschemawithdirectives) instead.

+ * ## Example
+ * Given a schema, convert it to SDL
+ * ```
+ * const sdl = printSchema(schema);
