Requiring docker when supplying --out

Is there an existing issue for this?

Describe the bug

I run into an error when running nixpacks build with the --out param:

Error: Please install Docker to build the app https://docs.docker.com/engine/install/

To reproduce

nixpacks build . --name some-name --out path/to/out/dir --no-cache --config assets/nixpacks/golang.toml --build-cmd "go build -o out ./path/to/source"

Expected behavior

Docker should not be required for generating a Dockerfile

Environment

Alpine 3.19
Nixpacks 1.24.6

Maybe related: #1115

Original issue stated that it would occasionally work. That was wrong. I embed nixpacks within a docker container as part of my CI pipeline. When building the container locally, the layer would be cached and it would use 1.24.5 while when the pipeline built the container, it would instead pull the latest of 1.24.6. Forcing 1.24.5 fixes the issue.

For context, I use the out parameter to generate the docker file which is then zipped, sent to S3, to be built by Kaniko on Fargate.

Same here.

Generating Dockerfile with Nixpacks and building the image on my Kubernetescluster with Buildah. Getting the same error message.

As @lamebear stated: Works as expected with 1.24.5
