inconsistent Requires-Dist leads to ImportError with 0.25

[cburroughs]

5fa62e1 set a runtime check with required_tensorflow_version = '2.18', but https://github.com/tensorflow/probability/blob/v0.25.0/setup.py#L52 still has the Requires-Dist set to 2.16.

This will lead to an import error like:

E   ImportError: This version of TensorFlow Probability requires TensorFlow version >= 2.18; Detected an installation of version 2.16.2. Please upgrade TensorFlow to proceed.

which could be avoided if the Requires-Dist matched.

thank you!

upgrading tensorflow manually should work for now, right?

Yes, a user can work around this by manually satisfying the dependency.
