Setup:
Set "files.simpleDialog.enable": true.

Testing:

• You'll need to write a very small extension. The hello world sample is always a good place to start.
• Add a call to vscode.window.showOpenDialog({ openLabel: 'some message' } in your extension.
• Run your extension. Verify that your openLabel is shown as the label for the accept button in the simple file dialog.
