### Reproduction steps

Add a server configuration under Manage Jenkins > Configure System as described in the doc but without credentials.
Add pipeline steps:
```groovy
stage('Edit JFrog CLI') {
steps {
jf('config show')
jf('config edit arti_server --user=my_user --password=***')
jf('config show')
}
}

stage('Build and Publish') {
steps {
jf('mvn --project ${PROJECT_ID} clean install')
}
}
```

### Expected behavior

The user and password should be add to configuration without removing server URLs

### JFrog plugin version

1.5.0

### JFrog CLI version

2.53.2

### Operating system type and version

Linux

### JFrog Artifactory version

7.68.19

### JFrog Xray version

_No response_

Start by reproducing the Manage Jenkins configuration and pipeline steps with JFrog plugin 1.5.0, focusing on the transition from `jf config edit` to the later `jf mvn` call. Done means adding user and password preserves the configured server URLs so the subsequent Maven command no longer reports that the URL is required.
