"Nitpick" in documents goes to a dead link

[BruceEckel]

On this page: https://returns.readthedocs.io/en/latest/pages/contrib/mypy_plugins.html#mypy-plugins

The second sentence below: https://returns.readthedocs.io/en/latest/pages/contrib/mypy_plugins.html#configuration

Is: You can also use nitpick tool to enforce the same mypy configuration for all your projects.

That link goes to a "buy this domain" page.
