improve npm publish steps to account for issues revolving around import / export statements

[jakeburden]

If someone knows how to publish an ES2015 package that uses import and export statements and is willing to help out the openshare community that would be amazing ✨

Users trying to install this package were running into some issues, so I've recently republished the prebuilt version of this package (which webpack warns against about doing). I love that openshare uses es modules (import / export statements), but I don't have a time to look into this at the moment.

Thank you in advanced 😄
