DOC: pandas.Index.astype says it raises ValueError instead of TypeError

[coelhudo]

Location of the documentation

The documentation is located at https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Index.astype.html

Documentation problem

The documentation says " When conversion is impossible, a ValueError exception is raised." However, checking the code it can be seen that a TypeError is raised instead of ValueError.

Suggested fix for documentation

Just change ValueError to TypeError in the docstring.
