Ruggeduino overrides pinmodes at initialisation

[WillB97]

This causes pin modes set in the setup() routine in the ruggeduino to be overriden.

j5/j5/backends/hardware/sr/v4/ruggeduino.py

Lines 49 to 50 in 86985e9

	for pin_number in self._digital_pins.keys():
	self.set_gpio_pin_mode(pin_number, GPIOPinMode.DIGITAL_INPUT)

This is intentional behaviour to ensure that the modes in Python match the modes on the Ruggeduino.

[WillB97]

This currently silently breaks the code of every student who follows an arduino guide as the recommended code layout is to configure the pinmodes in the setup. This is then overridden by j5.

Then we need to update the docs. This is how the old sr API behaved also, so I'm surprised it's gone unnoticed for this long.

Additionally, there are possibly teams who are relying on this behaviour as we document the initial pin modes.

So at the very least, we can't change this until SR2024
