[JENKINS-75610] docker-workflow doesn't set DOCKER_HOST

Given a pipeline with a custom `DOCKER_HOST`:

 

node {

    stage('Testing LIMA VM') {

        docker.withServer('unix:///home/user/.lima/lima-test/sock/docker.sock') {

            docker.image('jenkins/agent').inside {

                sshagent(['user_b']) {

                    sh 'ssh-add -l'

                }

            }

        }

    }

}

I get this error: 

ERROR: Failed to run ssh-agent: Error response from daemon: No such container: 85b4f32a54d1292....

 

I've investigated the issue and I think that https://github.com/jenkinsci/docker-workflow-plugin/blob/19b84d6e042ec18c159487b59e21f9644eb14e5b/src/main/java/org/jenkinsci/plugins/docker/workflow/WithContainerStep.java#L263 should inject `DOCKER_HOST` into the `starter` envs (using the value from `envHost`)
