DOC: Move bug fixes in whatsnew for 2.2.0 into the appropriate subsection

[rhshadrach]

We've started adding any bug fixes directly below the Bug fixes section rather than in the proper subsection they belong.

pandas/doc/source/whatsnew/v2.2.0.rst

Lines 279 to 287 in 21689e5

	Bug fixes
	~~~~~~~~~
	- Bug in :class:`AbstractHolidayCalendar` where timezone data was not propagated when computing holiday observances (:issue:`54580`)
	- Bug in :class:`pandas.core.window.Rolling` where duplicate datetimelike indexes are treated as consecutive rather than equal with ``closed='left'`` and ``closed='neither'`` (:issue:`20712`)
	- Bug in :func:`pandas.api.types.is_string_dtype` while checking object array with no elements is of the string dtype (:issue:`54661`)
	- Bug in :meth:`DataFrame.apply` where passing ``raw=True`` ignored ``args`` passed to the applied function (:issue:`55009`)
	- Bug in :meth:`pandas.DataFrame.melt` where it would not preserve the datetime (:issue:`55254`)
	- Bug in :meth:`pandas.read_excel` with a ODS file without cached formatted cell for float values (:issue:`55219`)
	-

Each of the notes in the lines above should be moved to an appropriate subsection below.
