v10.1.0

Changed

• Turns out there were more changes needed for Gulp v4 😆
  Specifically, regarding runSequence (which no longer works in Gulp v4). Have converted these tasks to use gulp.series and gulp.parallel instead. This ahs been tested with how HomeWeb uses its default task – this is likely to need more specific testing/updates if/when we migrate this into other applications that use this package).
