xiao-ble/ble-led-server needs additional permission

Looks like tinygo-org/bluetooth package does not support Characteristic.Write() on macos and linux. It only supports WriteWithoutResonse(). Need to add bluetooth.CharacteristicWriteWithoutResponsePermission in order for connections to xiao-ble ble-led-server.
