Setup wizard has "arming" check for planes, which is not required

Planes don't need to be armed at the transmitter, so this text is confusing.


Start by locating the Mission Planner setup wizard and the plane-specific arming check shown in the attached screenshot. Confirm which wording is displayed for planes and update it so the wizard no longer implies that transmitter arming is required. Done means the confusing text is corrected and the plane setup flow no longer presents this requirement.
