fix bower.json and component.json version

mapbox/leaflet-omnivore@724ede9b is missing this change.
Bower complains when installing that tag 0.2.0 is pretending to be 0.1.2.

I don't think you will be able to publish a new 0.2.0 tag without npm complaining. Maybe a 0.2.1 ?

You may use the [webpro/release-it](https://github.com/webpro/release-it) to assist you when creating a release. Doing it manually is a pain, and the `release-it` utility work quite well.
