Feat: usage of Gradio Tool.from_gradio based on URL

[davidberenstein1957]

I think it could be useful to allow initialising a Gradio tool using a direct URL. This would allow people to use Gradio tools that are hosted outside of the Hub. We could potentially also explore if this plays together well with Tool.from_spaces where we internally use gr.load("gradio/question-answering", src="spaces").launch() to launch a local version of the Space of choice.

Happy to work on / explore this approach.

@davidberenstein1957 Tool.from_gradio did exist in transformers.agent, I removed it when creating smolagents because it felt like a less practical version of Tool.from_space and it had bugs, but happy to re-open it if you want to take a look! 😃

I think Tool.from_space is a nice option when you prefer to use something something local. Let's see if there is some engagement on the issue.
