Subject: [PATCH] Add Docker image for Goose

Fixes #1072

Add Docker image support for Goose.

* **Dockerfile**: Add a `Dockerfile` to build the Goose Docker image using a multi-stage build to minimize the final image size. Install necessary dependencies, build the Goose binary, and set the entrypoint to the Goose binary.
* **GitHub Actions Workflow**: Modify `.github/workflows/build-cli.yml` to add a new job for building and publishing the Docker image. Use the `docker/build-push-action` to build and push the image, set the image name and tags based on the GitHub repository and branch, and add steps to log in to Docker Hub and push the image.
* **README.md**: Update `README.md` with instructions on how to pull and run the Docker image, including the Docker Hub repository URL and example commands to run the Goose Docker container.
