Wrong PICO_FLASH_SIZE_BYTES for Tiny2350

[polhenarejos]

Pimoroni's Tiny2350 has 4MB of flash room, not 8, as they describe in their website:

https://shop.pimoroni.com/products/tiny-2350?variant=42092638699603

I have a Tiny2350 and I can confirm that picotool reports 4MB.

pico-sdk/src/boards/include/boards/pimoroni_tiny2350.h

Line 89 in efe2103

#define PICO_FLASH_SIZE_BYTES (8 * 1024 * 1024)

I spoke to them but I did not get any answer and not sure how to proceed or who is the responsible for maintaining the board's header definition.

[lurch]

I already fixed this as part of #1814 😀
Fixed on develop branch.
