Add FlowNodeConsoleUrlProvider interface for console URLs

[das7pad]

• Part of Link to stages view from GitHub Checks pipeline-graph-view-plugin#1266

This interface provides a method to retrieve console URLs for specific FlowNodes in Jenkins, allowing for richer visualizations in the Pipeline Graph View.

Testing done

Implement public String getConsoleUrl(Run<?, ?> run, FlowNode node) in PipelineConsoleViewUrlProvider and adopt that.

See logs URLs on GitHub checks point at the step.

Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests that demonstrate the feature works or the issue is fixed

@das7pad see jenkinsci/pipeline-graph-view-plugin#1266 (comment), ConsoleUrlProvider is for internal Jenkins-to-Jenkins links, the case you care about is an external link, so it should be a new API method in https://github.com/jenkinsci/display-url-api-plugin instead.

The general idea makes sense though and I think it will be helpful
