[Feature Request]: API Docs view only

[Spaceginner]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

By adding some flag as the starting argument, the webui will launch in api docs view mode only, which will allow to only view API docs.

Proposed workflow

1. Go to webui-user.bat or webui-user.sh
2. Add flag --api-docs-only to the starting argument
3. Launch it

Additional information

This will be useful, as sometimes I need only to view API docs and not to interact with AI models itself and loading times are quite long. As an implementation, it can just redirect from http://127.0.0.1:7860/ to http://127.0.0.1:7860/docs

As someone who has work with this API a lot, I can see how this could have some use. 😌
