Historically, boards with no built-in display have not had a
board.DISPLAY
property.Soon, with adafruit/circuitpython#10028, any board with displayio will have a
board.DISPLAY
property. This property will beNone
if no display is configured, or a truthy non-None
value if a display is configured (including dynamically at runtime).This revised check will work on both old and new circuitpython versions.
