Corrected argument types

This is part of #8362 - I'm hoping to break down that PR into easier-to-review chunks.

1. Pillow/Tests/test_image.py

   Line 670 in af3b904

   im.remap_palette(None)

   
   should use a list, as per

Pillow/src/PIL/Image.py

Lines 2138 to 2140 in af3b904

	def remap_palette(

2. Pillow/Tests/test_image.py

   Line 773 in af3b904

   exif.load(None)

   
   should use a bytestring, as per

   Pillow/src/PIL/Image.py

   Line 3952 in af3b904

   def load(self, data: bytes) -> None:

   Pillow/src/PIL/Image.py

   Lines 2250 to 2256 in af3b904

   	self,
   	size: tuple[int, int] | list[int] | NumpyArray,

   	reducing_gap: float | None = None,
