[Docs][Python] Add Hyperbolic Trig functions to API docs

[AlenkaF]

Describe the enhancement requested

#44630 added hyperbolic trigonometric functions to the Arrow C++ compute kernels together with the tests in PyArrow. We should also add the list of these new functions to PyArrow API reference documentation (https://github.com/apache/arrow/blob/main/docs/source/python/api/compute.rst#trigonometric-functions).
