Describe issue

Trying to run act to locally test CI workflows for a Python project on macOS without using Docker, getting the following error:

WARN  ⚠ You are using Apple M-series chip and you have not specified container architecture, you might encounter issues while running act. If so, try running it with '--container-architecture linux/amd64'. ⚠
