Subject: [PATCH] chore(gulpfile): ignore `node_modules` folders in examples

This should speed up watching as it is unusual to update files in these
folders during normal development.

If you do change files in an example `node_modules` folder then you must
restart the gulp task to trigger the shredder and reload.
