[Suggestion] Change GIF in software setup instructions to just the ESP32

[keerats7]

While building my frog, I saw in the software section of the setup the GIF of the completed frog. That led me to think I needed to build the frog first and then come back to the software section. That ended up being the wrong choice since I had to basically disassemble the top of the frog to get access to the ESP32 (for pressing the boot and reset buttons). I could've thought it through much better! But either way, I think if the GIF was instead a cable going into just the ESP32 (like how the builder would be doing it at that step), there would be less confusion.
