Figure 9 is wrong in the Python SDK documentation

[jlnprssnr]

In the Python SDK documentation, figure 8 is used a second time instead of figure 9, which should show the wiring for a SH1106-based OLED.

@kilograham or @aallan Could you move this to https://github.com/raspberrypi/pico-micropython-examples please?
The underlying cause is that https://github.com/raspberrypi/pico-micropython-examples/tree/master/i2c/1106oled is using the wrong image.
