docs: meta.pycqa.org code-of-conduct hyperlinks are not redirecting as expected.

Hello,

The (Contributor Covenant) Code of Conduct for PyCQA does exist and appears to be hosted at: https://meta.pycqa.org/code-of-conduct.html

However, currently at commit acbcec4 there are two hyperlinks in this repository that point to the Code of Conduct using the URL: http://meta.pycqa.org/en/latest/code-of-conduct.html and this returns an HTTP 404 response when I request it.

The hyperlink locations in the documentation are:

• CONTRIBUTING.rst line 100
• docs/developer.rst line 115

I can offer a pull reqeuest to update the hyperlinks if that would be helpful; however if these hyperlinks previously functioned correctly and are expected to, then alternatively a webserver-side configuration check may be required.

Thanks!
