"python3 not found" during docker build

When trying to build the docker image on my rpi5, it builds for a while and then exits with an error: "python3 not found".

hi,

Thanks for having reported this. Python3 is a (relatively) new requirement for building XNNPACK.

I just committed the fix.

Thank you, Vito
