Remove alias in pandas docs for numpy.random.randn

[datapythonista]

See the discussion here: pandas-dev/pandas#28038 (comment)

In pandas we have a header variable that we inject at the top of all documentation pages. One of the things there is randn = np.random.randn, which is a very bad idea that is only useful to confuse users.

With a quick grep I could just find a single case where that is used:

whatsnew/v0.10.0.rst:  In [58]: p4d = Panel4D(randn(2, 2, 5, 4),

We should replace that case to use np.randon.randn explicitly, remove that line from the header in doc/source/conf.py and see in the doc builds if nothing fails after that change (this can be done locally or also in the CI).

Hi @marc.
Is this for testing?
I can infer that the issue is with using 'randn' as variable name not change np.random.randn to np.randon.randn.
Please clarify, I will send PR for this

that's code that shows in the docs, I don't think in that specific case the code is even run by Sphinx, since that Panel4D class doesn't exist anymore.

The issue is that randn = np.random.randn is a very bad idea, and we'll make that code public now (we run it in the docs, but we don't show it now).

Ok, I will send a PR and tag you.

@WuraolaOyewusi I think this was merged, feel free to close this issue.
