Running Colima with GitHub Actions on "macos-latest"

[bennycode]

I tried to run Colima in GitHub Actions using the macos-latest runner, but the setup failed. I then checked the setup-docker-macos-action repository, which mentions that only macos-13 is supported and that arm64 processors (M-series) used on macos-14 and later images are unsupported due to the lack of nested virtualization.

I also noticed that the Colima repository itself uses the macos-15-intel runner: https://github.com/abiosoft/colima/pull/1425/files

Could you clarify this in your documentation or provide some guidance on the recommended way to run Colima in GitHub Actions CI?

Unfortunately, there are no real alternatives until Apple supports nested virtualization on macOS guests.
