Fix ci

fix #265

• update action script
• use toolchain cache instead of node xpm
• also update gcc from 9.3.1 to 10.2.1

This is a bit of self promotion of a GitHub Action I mantain, so apoligies if it's unwanted, and please do feel free to ignore the message. Hopefully is more useful than spam.

I was going through old GitHub notifications and noticed this, so just to let you know that with https://github.com/carlosperate/arm-none-eabi-gcc-action, which does automatic caching, something like this could condense to just:

- uses: carlosperate/arm-none-eabi-gcc-action@v1
  with:
    release: 10.2.1

Obviously the current CI confirg works well, so I'm not suggesting it should be changed, just something that could be useful in the future 👍

@carlosperate wow, your action looks great, lots of Adafruit repo need gcc and this will help to tidy the ci yml. I will try to start migrate some as starter. Thank you for the suggestion.

Glad to hear that! Let me know if you have any questions, I'd be happy to help.
