[Feature Request]: Menu Shortcut for New Pipeline/Workflow in File Explorer

### What would you like to happen?

Objective: Enhance the Apache Hop File Explorer by adding "New Pipeline" and "New Workflow" options directly to the right-click (context) menu of folders.

Current State: Users must use the top "File" menu or shortcuts (Ctrl+N) to create new files, which requires extra navigation to save them in the correct directory.

Proposed Solution:

Context Integration: Add two new actions to the folder context menu: "New Pipeline (.hpl)" and "New Workflow (.hwf)".

Behavior: When selected, the system should prompt for a file name and automatically create the file within the selected folder.

User Experience: Upon creation, the new file should automatically open in the main editor tab for immediate development.

### Issue Priority

Priority: 3

### Issue Component

Component: Hop Gui

Start in the Apache Hop File Explorer and trace how the folder right-click menu and existing File menu or Ctrl+N actions create files. Add the two requested folder actions, including filename prompting and opening the created file in the main editor tab. Done means both .hpl and .hwf options create files in the selected folder and open them for editing.
