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

[jenkins-infra-bot]

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

docker-workflow-plugin/src/main/java/org/jenkinsci/plugins/docker/workflow/WithContainerStep.java

Line 263 in 19b84d6

@Override public Proc launch(Launcher.ProcStarter starter) throws IOException {

should inject `DOCKER_HOST` into the `starter` envs (using the value from `envHost`)
