"See History and License" link redirects to current page

Hi lovely pypa folks,

I went to click on the "See History and License" link at the bottom of the page today and noticed that it just redirects to the current page, which I'm guessing isn't intended behavior. I did a quick amount of poking around to see if I could figure out where it should go and it wasn't immediately obvious to me, so I'm sorry I can't give more info than that! Hope this helps.

Looks like this comes from https://github.com/python/python-docs-theme/blob/6ed468afa48ad3f03c117ef7b05df4806d89a674/python_docs_theme/layout.html#L129 and we should define a license_file (and also create that file).

This is due to python/python-docs-theme#89 and should be fixed by python/python-docs-theme#90 , FYI
