Running Colima with GitHub Actions on "macos-latest"

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](https://github.com/douglascamata/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?
