busio.I2C gets imported only for the type hint here:

class INA219:
    [...]
    def __init__(self, i2c_bus: I2C, addr: int = 0x40) -> None:

If the import of busio.I2C fails, then the definition of INA219 fails with:

NameError: name 'I2C' is not defined

So, instead of passing, I assign a None value to I2C simply for avoiding that error.

This PR is similar to this one done for another module: adafruit/Adafruit_CircuitPython_ADS1x15#93
