Force old version of numpy in `noise.ipynb`

[markmcd]

This currently works in colab, but will break when it's updated, and breaks in the TF docs publishing infra.

The TFQ code is referencing NumPy's np.float, which is removed in v1.24. Details here. This is quick hack to get the docs working again.
