Access to `showInputBox`

Steps or JS usage snippet reproducing the issue:

I think it would be nice to have access to showInputBox to add additional inputs to Action Commands.

I do see we can able input the line number when open the go to line is selected from the palette. But I could not find a way to add action commands to accept quick inputs to execute the action.

  private editorDidMount(editor, monaco) {
    editor.addAction({
      id: 'my-unique-id',
      label: 'Test: Add value',
      keybindings: [monaco.KeyMod.CtrlCmd | monaco.KeyCode.F10],
      contextMenuGroupId: 'Test',
      contextMenuOrder: 1,
      run: function (ed) {
           showInputBox({
           acceptInput: 'accept input',
           prompt: 'add any value',
           ignoreFocusOut: true,
         })
      },
    });
    editor.focus();
    this.monaco = monaco;
    this.editor = editor;
  }

Start by tracing the existing Go to Line input flow and the public addAction API, focusing on how an action's run callback can access editor services. Done means custom actions can invoke showInputBox with options such as prompt and ignoreFocusOut, with the input result available to the action.
