The amazon and google providers don't include necessary datafiles in them.

They were previously included in the sdist via MANIFEST.in (see https://github.com/apache/airflow/pull/12196) and in the bdist via include_package_data from the top level setup.py

Both of these are currently missing.

I've put this against 2.0.0-beta1, it _could_ be changed separately as providers are separate releases.
