camera: fix missing "Action" scene mode in camera settings

scene-mode-values parameter was missing "action" value, causing the
Scene Mode setting menu to get messed up (missing icon, incorrect text
labels).
Added back in "action" value, and configured to used SCENE_MODE_SPORTS
settings, as this is the same as SCENE_MODE_ACTION according to docs:
