Broken Urls For Server API Schema

[guomanmin]

For "The schema is here, rendered nicely here." Both links are broken.

Also the subsection terminals API is missing from the table of contents

@guomanmin thanks for your report- can you specify where you are seeing these links? That wording doesn't appear in this repository.

It seems invalid:
https://github.com/jupyter/notebook/blob/main/notebook/services/api/api.yaml
https://petstore.swagger.io/?url=https://raw.githubusercontent.com/jupyter/notebook/master/notebook/services/api/api.yaml

@priyanshukumar397 that URL moved, but the question I have it about where there is a link pointed to that URL?
