Use the published experimental declarative plugins

[octylFractal]

Waiting on gradle/declarative-gradle#61 to fix & publish a new version before being ready.

@tresat I think the failures are unrelated to these changes, do you know if main-declarative has been building for you?

IDK. The :app:connectedDemoDebugAndroidTest task that failed in the Build / androidTest (30) (pull_request) also fails for me locally with my current changes (if I have a running device in the emulator for it to test on), but with a different error: Test run failed to complete. Instrumentation run failed due to Process crashed..

I'm not sure exactly what is contained in this published version of the declarative prototype, but it's probably less important than the significant changes waiting on review there that will support declarativizing NiA's application projects. I'd wait for those to be merged and a new plugin version published before spending much time troubleshooting this build.
