multi-platform builds fail

### Description

When running `docker build --platform linux/amd64,linux/arm64 .` I get:
```[+] Building 0.0s (0/0) docker:colima
ERROR: Multi-platform build is not supported for the docker driver.
Switch to a different driver, or turn on the containerd image store, and try again.
Learn more at https://docs.docker.com/go/build-multi-platform/
```

Per this issue [comment](https://github.com/abiosoft/colima/issues/44#issuecomment-955595041) it sounds like this should work out of the box.

buildx says it's using Colima:
``` λ docker buildx ls
NAME/NODE DRIVER/ENDPOINT STATUS BUILDKIT PLATFORMS
colima* docker
\_ colima \_ colima running v0.11.7+435cb77e369c linux/arm64, linux/amd64, linux/amd64/v2
default error
desktop-linux error

Cannot load builder default: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Cannot load builder desktop-linux: Cannot connect to the Docker daemon at unix:///Users/vince/.docker/run/docker.sock. Is the docker daemon running?
```

I tried recreating the buildx builder, recreating the Colima instance and always get that message which refers me to Docker Desktop docs to enable the "containerd image store". Is there an equivalent step for Colima or some other step I need to take?
