Keyboard Shortcuts: Paintbrush stroke needs points, so it isn't listed

#7592 documented brush.freehand's brush as optional, so the shortcut editor took it for a
command that runs without params and listed it, and listed_commands_run_from_a_key_without_a_missing_param
fails on main: a key press can't give the stroke's points. It joins NEEDS_A_PARAM with the
other commands that need a point.
