Fix Text classification with TensorFlow Hub

[dnoliver]

• install tf_keras
• use tf_keras model and layers

Run into a problem while running the cell:

Only instances of keras.Layer can be added to a Sequential model. Received: <tensorflow_hub.keras_layer.KerasLayer

Applied the fix described in https://github.com/tensorflow/tensorflow/issues/63849. After the change, the notebook works end to end. But I think this actually downgrades the tf_keras support from 3 to 2, as noted in https://github.com/tensorflow/tensorflow/issues/63849#issuecomment-2011748852.

If the notebook is supposed to work as is, without this fix applied, then this PR shows how to apply the workaround to the notebook until the main issue is figured out :)

Thank you @dnoliver . Please review the CLA .

@MarkDaoust @markmcd keras. instead of tf_keras. or both in layer names?
