Remove bintray maven repository

[JulianKingman]

In the build.gradle file, it uses the following dependency under repositories:

maven {
     url 'https://dl.bintray.com/intercom/intercom-maven'
   }

Bintray has been shut down and will no longer work.

Any update on this?

I've upgraded to intercom's official library, it's not too hard. @intercom/intercom-react-native

[walterholohan]

Any update on this? Should we migrate to the official library from Intercom or will this library be maintained?
