Reorganize Guides in a more logical order

[abidlabs]

The ordering of the Guides currently doesn't make sense, as we introduce gr.Interface in the Quickstart, then cover all sorts of key features that are quite advanced, and then lots of details related to sharing, before jumping back to gr.Interface.

Now, I think the ordering makes more sense. These are the new sections

1. Quickstart
2. Interface
3. Additional Features (key features and sharing details moved here. I've also separated key features into individual guides since we should add more details to these guides -- will do in a separate pr -- and also for seo purposes)
4. Blocks
5. ChatInterface and Chatbots
6. Custom Components
7. Tabular DS and Plots
8. Clients and Lite
9. Other Tutorials (moved integrations to this section)

I've also fixed some typos, etc. I want to rework the guides some more but I didn't want to mix refactoring & other changes in a single PR.

Nice! I agree this is much better.

Can you add redirect routes for old links? Not a big deal but can be helpful https://github.com/gradio-app/gradio/blob/main/js/_website/src/routes/redirects.js

Is it needed, I thought moving the guides to different sections does not affect the url, e.g. https://www.gradio.app/guides/the-interface-class

[aliabd]

yeah you're right, i meant for the ones you removed, which i guess is just key-features

[abidlabs]

right, will add

Thanks @aliabd for the review!
