[Docs] dependency_links removal documentation

[plocket]

Summary

Thank you for your work on this package. I'll admit I'm pretty new to the python ecosystem, so I apologize if I'm off base here.

I was reading the steuptools documentation of dependency_links of the latest version. At the top, it has a warning that "Dependency links support has been dropped by pip starting with version 19.0 (released 2019-01-22)." I was confused about what to do next, since I needed to specify a link to a GitHub repo. I would have found it useful if there were a link to the current documentation on how to achieve the same result with current versions of pip.

I found this link that had a bit more up to date information: https://setuptools.pypa.io/en/latest/userguide/dependency_management.html#direct-url-dependencies. It doesn't line up with what I found at https://packaging.python.org/en/latest/specifications/dependency-specifiers/#examples, though, which uses a zip address. I'm not sure what the best edit would be.

By the way, the issue template here says there's a "View on GitHub" link on every documentation page, but I was unable to find that on pages on the documentation site.

OS / Environment

Irrelevant.

Additional Information

I think adding to these docs can help developers understand how to solve a problem with less digging and be more up to date with the specs.

Hi @plocket, thanks for the feedback.
I am not sure if the docs used to have the button and somehow the template changed or not, but I just enabled the edit on github button to show up in the docs (there is a pencil icon on the top right corner of the page now). The eye icon should also show things in GitHub now.

https://setuptools.pypa.io/en/latest/userguide/dependency_management.html#direct-url-dependencies. It doesn't line up with what I found at https://packaging.python.org/en/latest/specifications/dependency-specifiers/#examples

Could you please specify how they don't line up? (zip is only of of the possible formats accepted).
