10.0.0.dev0 version bump

[radarhere]

4f7070e set the next version of Pillow as

Pillow/src/PIL/_version.py

Line 2 in 4f7070e

__version__ = "9.6.0.dev0"

However, we have been listing Pillow 10.0.0 in the code as the Pillow version due out in the next quarter on the 1st of July.

Pillow/src/PIL/_deprecate.py

Line 49 in 4f7070e

removed = "Pillow 10 (2023-07-01)"

Pillow/src/PIL/ImageTk.py

Lines 173 to 174 in 4f7070e

	:param box: Deprecated. This parameter will be removed in Pillow 10
	(2023-07-01).

Pillow/src/PIL/ImageShow.py

Lines 118 to 120 in 4f7070e

	Before Pillow 9.1.0, the first argument was ``file``. This is now deprecated,
	and will be removed in Pillow 10.0.0 (2023-07-01). ``path`` should be used
	instead.

We've also been listing it in the docs as that date - https://pillow.readthedocs.io/en/stable/deprecations.html#tk-tcl-8-4

I think this was just an error. Happy to start a discussion if there is other thinking.

Yes, that's right! 10.0.0 is next!
