Rename *Bright/Contrast* to *Brightness/Contrast* in order to avoid the use of shortened names and improve consistency within Blender and with industry conventions. Reasoning: The modified color characteristic is called *brightness*, not *bright*. You don't modify the *bright* of an image. This also interferes with search in case someone searches for brightness, producing no results. *Note: This patch should only touch UI names which do not need versioning. It leaves the actual property name in nodes for a future breaking release.* Pull Request: blender/blender#104998
