[JENKINS-52761] withDockerRegistry fails to login with complex password

Jenkinsfile:

```
stage('Deliver') {
steps {
withDockerRegistry([credentialsId: 'docker-creds', url: '']) {
sh "docker push imagename"
}
}
}

```

Error:

```
$ docker login -u username -p ******** https://index.docker.io/v1/
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get https://registry-1.docker.io/v2/: unauthorized: incorrect username or password

```

Workaround:

Change Docker Hub password from something complex (e.g. "]GT~XMRZwWc6]dUg:NMs") to something very simple (e.g. "insecurepass"). Using a simple password that is very long (e.g. "verylongpasswordhere") works fine too.

`docker login` using complex password from the CLI works just fine.
