Exif: MakerNote enums spelled differently

[mixmastamyk]

https://github.com/python-pillow/Pillow/blob/main/src/PIL/ExifTags.py#L156

MakerNote = 0x927C

https://github.com/python-pillow/Pillow/blob/main/src/PIL/ExifTags.py#L355

Makernote = 37500

These names should be consistent. Also, some values specified in hex and others in decimal is a bit messy, though merely cosmetic.

I've created #8615 to resolve this.

Also, just as an aside - you've linked to my fork, rather than to this repository.

Thanks. However, it would probably be good to carry the old spelling for a while, marked deprecated as a courtesy. Otherwise will break some users. Unless there is a big breaking release coming up.
