Add API Documentation to each instance

[mdg-pnw]

A great example of this is the way that BookStack handles its API documentation. If you load an instance of BookStack, the API documentation is also at https://domain.com/api/docs

The nice thing about this is that all of the API endpoints automatically have the domain populated. So instead of:

The actual URL would be the hostname.

Additionally, you'd probably want to add a link to the instance's API Docs right on the same page that you create the Access Token.

Alternatively, if you don't want to integrate the API Docs into the instance, could you add a link to the API Document on the Access Token view for quick reference?
