Help: find_package: Tweak change description
A change note for support added in CMake 3.16 reads:
.. versionadded:: 3.16
Added the ``CMAKE_FIND_USE_<CATEGORY>_PATH`` variables to globally disable
various search locations.
but two of the variables added are CMAKE_FIND_USE_PACKAGE_REGISTRY
and CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY
. Just CMAKE_FIND_USE_<CATEGORY>
is a better description.
