Subject: [PATCH] Update README.md with DOCKER_HOST env var instructions (#565)

I had an error pulling local images. Setting the DOCKER_HOST env var fixed this problem for me. This has has been mentioned in issues such as https://github.com/wagoodman/dive/issues/542#issuecomment-2267720375

+if you are using an alternative runtime (Colima etc) then you may need to specify the docker host as an environment variable in order to pull local images:
+```bash
+   export DOCKER_HOST=$(docker context inspect -f '{{ .Endpoints.docker.Host }}')
+```
