Incorrect documentation for how to enable napoleon extension's `napoleon_type_aliases` setting

[kbattocchi]

Describe the bug

The documentation at https://www.sphinx-doc.org/en/master/usage/extensions/napoleon.html#confval-napoleon_type_aliases incorrectly states that napoleon_use_param must be set to True for napoleon_type_aliases to work:

sphinx/doc/usage/extensions/napoleon.rst

Lines 514 to 517 in a6032e8

	.. confval:: napoleon_type_aliases
	A mapping to translate type names to other names or references. Works
	only when ``napoleon_use_param = True``. *Defaults to None.*

Contrast with the extension's own docstring, which correctly notes that it is actually napoleon_preprocess_types that must be True:

sphinx/sphinx/ext/napoleon/__init__.py

Lines 237 to 239 in a6032e8

	napoleon_type_aliases : :obj:`dict` (Defaults to None)
	Add a mapping of strings to string, translating types in numpy
	style docstrings. Only works if ``napoleon_preprocess_types = True``.

How to Reproduce

Enable a set of aliases in napoleon_type_aliases and set napoleon_use_param = True; those aliases will not be used. If napoleon_preprocess_types is set to True instead then the aliases will be used correctly.
