[TBD] remove android/README.md with Maven publishing info - DRAFT WIP

[brodycj]

with TODO items:

• capture the information somewhere such as in https://github.com/brodybits/create-react-native-module/issues
• add a pointer to this information in the console log output

I am planning a different solution:

• raise a new PR to make the Maven publishing support optional, not enabled by default (see PR DRAFT RFC: remove extra android build support #403)
• only include the information, somewhere, if the Maven publishing support is enabled
