Release a new tag version with the updated babel version

[jasalguero]

The PR #41 upgraded the babel version which is done to resolve the Ember Global usage deprecation warning, which block upgrading to Ember 4. But the last tag as of today (2.0.2) doesn't include this change, so the only option is to point directly to the master branch...

Published 2.1.0. Hopefully this helps.
