Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/docs/reference/api/pandas.Index.html

Documentation problem

While infer_objects() is listed as a method for pandas.Index, the link to the actual method documentation is missing.

Suggested fix for documentation

Probably have to add Index.infer_objects into the conversion section of pandas/doc/source/reference/indexing.rst
