Describe the bug https://docs.wokwi.com/parts/wokwi-pi-pico#exporting-uf2-binary doesn't work. As in, the UF2 file is not accepted by the Pi Pico bootloader.

To Reproduce Project is here: https://wokwi.com/projects/395639736344965121 chip is (now) a bog standard RP Pico 2020 from them (verified good via Circuit Python and Arduino IDE)

Open project
Start simulation, wait for compile, verify simulated LED does blink.
Stop simulation
Click in editor
Press F1
Scroll to "Download UF2 Binary" and click it.
Hold down bootloader button on RP Pico and plug it in.
Drag firmware file to the Flash drive "RPI-RP2" when it appears.
Eject the drive
Power cycle RP2 /without/ holding down the bootloader button

Expected behavior EXPECTED: LED on RP2 blinks. FOUND: It doesn't.
