Github link to tf.nest.map_structure is broken in the docs
@chmendoza You're right, there have been reports already of some TensorFlow API GitHub source code links not working correctly.  It's a known issue. Tensorflow has been released at 2.15.0.post1 ([see pypi](https://pypi.org/project/tensorflow/)), so the docs reflect like that. Seems like the repo is missing the appropriate tag for which an internal fix was raised. Thank you! Apologies if creating noise, but here is another one with a broken link: https://www.tensorflow.org/api_docs/python/tf/nn/softmax @chmendoza Yes, there are a few other apis are also there which are having the same issue as you mentioned. We are expecting it to be fixed in the next release. 
Thank you!  This issue is stale because it has been open for 7 days with no activity. It will be closed if no further activity occurs. Thank you.

### Current behavior?

The "View source on Github" button in https://www.tensorflow.org/api_docs/python/tf/nest/map_structure takes me to a file that doesn't exist. Also, the doc says "Refer to [tf.nest](https://www.tensorflow.org/api_docs/python/tf/nest) for the definition of a structure.", but if I go to that link, there is no such definition.
