Command used with act

act push

Describe issue

When using a custom Docker image, my tests pass locally, but not in the actual GitHub CI.

Specifically, the installation of Cargo on the image works fine when run with act, but fails in the real environment, because rustup could not choose a version of cargo to run, because one wasn't specified explicitly, and no default is configured.

While I understand that the base runner environments aren't identical to the real ones, it was my understanding that using a custom image on top of that should create an entirely isolated environment. Am I misunderstanding something?
