Rename the "arduino" target to "arduino-uno" to better reflect the board it represents. The "arduino" name is kept as an alias that inherits from "arduino-uno" for backward compatibility. - Rename targets/arduino.json to targets/arduino-uno.json - Create targets/arduino.json as alias inheriting from arduino-uno - Rename board_arduino.go to board_arduino_uno.go - Update build tag from "arduino" to "arduino_uno" - Rename corresponding example files Signed-off-by: deadprogram <ron@hybridgroup.com>
