Short description

Installing only tfds-nightly via pip doesn't allow using it.
One needs to install apache-beam as well

• tensorflow-datasets/tfds-nightly version: TensorFlow Datasets: 4.9.6+nightly

Expected behavior
Either pip should install apache-beam on its own, or the documentation should tell to install it.
