Documentation problem

For example, in pandas.CategoricalIndex.add_categories, the source link jumps to the following source.This link is wrong.
As far as I've observed, the above methods all jump to the same wrong link.

pandas/pandas/core/accessor.py

Lines 98 to 99 in 40b2aa5

	def f(self, *args, **kwargs):
	return self._delegate_method(name, *args, **kwargs)

The source link should jump to the following location.

pandas/pandas/core/arrays/categorical.py

Line 943 in 40daf00

def add_categories(self, new_categories, inplace=False):

Suggested fix for documentation

Correct the source link.

@junjunjunk is this issue open to do?

@aflah02
This issue is open.
No one is assigned, so it's okay to take this issue.

Okk I'll try it then thanks 👍

@junjunjunk I have been trying to look at how redirects are made but couldn't find anything. Like in the browser page there is a source link which upon clicking redirects you however in the documentation at the current linked code there is nothing to indicate that it has been linked

pandas/pandas/core/accessor.py

Lines 91 to 92 in 5468223

	def f(self, *args, **kwargs):
	return self._delegate_method(name, *args, **kwargs)

Any idea on how links are actually taken care of in the Documentation?
