updat ein PlatformIO and marlin code couses error during compilation

[kdobrev]

This is the part that needs to be pulled MarlinFirmware/Marlin@c2decc3

And this is the thread https://community.platformio.org/t/trying-to-compile-marlin-2-1-2-for-ender-3-skr-mini-v2-0-board/33769/10 where I read how to solve my issue.

I ended up copy pasteing the whole code for Marlin.py form the official repo to my folder.
