android-studio-preview: init at 3.0.0.5 canary 6

Added the `androidStudioPackages` attribute containing both
the `stable` and `preview` channels.
Changed the attribute `andorid-studio` to point to
  `androidStudioPackages.stable`
Added the attribute `andorid-studio-preview` pointing to
  `androidStudioPackages.preview`

I have tested this package using the new koltin support,
no issues found yet.
