Add PNG File subsection to Pico Graphics documentation 
I added a subsection for PNG File support in Pico Graphics by copying and adapting the text from these release notes - https://github.com/pimoroni/pimoroni-pico/releases/tag/v1.20.4 - about the PNGdec functionality.

Phil Howard 8fc8a8ee06 CI: Rename tiny2040 to tiny2040_8mb. 
It was not super obvious that this build is specific to the 8mb
version of Tiny 2040.

Phil Howard d45daef654 MicroPython: Switch from MICROPY_EVENT_POLL_HOOK to mp_event_handle_nowait(). 
Note: Unsure if mp_event_handle_nowait() is the right answer in all cases,
but this seems to be what we want in our blocking loops.
