Subject: [PATCH] Update the "gulp jsdoc" task to account for API changes in
 the `mkdirp` package (PR 11772 follow-up)

I completely overlooked the fact that we had *one* occurrence of an asynchronous `mkdirp` call in the gulpfile, which thus breaks since the package now uses Promises rather than a callback function; sorry about that!
