ImageStyle content styles can be simplified

Look like this :not() selector does nothing:

diff --git a/theme/imagestyle.css b/theme/imagestyle.css

+                  max-width: 50%;
          }

          & .image-style-side {

The ImageResize feature adds own styles that override this max-width when enabled https://github.com/ckeditor/ckeditor5-image/blob/8e14b03f920e577cb9ddebd586c5721302abc578/theme/imageresize.css#L6-L7
