build: Disallow TensorFlow v2.16.1 (#2448)

* tensorflow v2.16.1 breaks tensorflow-probability at import time with
  the Keras v3.0 API breaking change. Until Keras v3.0 is adopted in
  tensorflow-probability, tensorflow v2.16.1+ can't be used.
   - c.f. tensorflow/probability#1795
* Note that Apple silicon machines should revert to installing
  'tensorflow' instead of 'tensorflow-macos' for tensorflow v2.16.1+.
* Note that macos x86 builds of tensorflow will be deprecated and no
  longer released from tensorflow v2.17.0+.
