gr.DuplicateButton appears even when run in a local environment

[hysts]

Describe the bug

Though the documentation of DuplicateButton says that it appears only on HF Spaces, it actually appears even when run in a local environment.

I can workaround by adding visible=os.getenv('SYSTEM') == 'spaces', but I guess it's supposed to work without doing this.

It's the documentation that needs to be updated. We decided to show the button even when running locally (but it would not have any effect) to avoid surprises when uploading to Spaces
