Could someone attach a "skip news" label?

Hi, I've come across the same problem that cocoatomo reported and checked some pages of all translated docs.

1. The current master code works fine when I've clicked the link at the top of bugs.html of the English doc.
   got 404 at the other language docs.

2. I've checked the HTML at https://docs.python.org/ja/3/bugs.html and the broken link is <a href="../index.html">Documentation</a>. The URL format of the bugs.html is like https://docs.python.org/{language}/3/bugs.html while the English doc URL is https://docs.python.org/3/bugs.html. This is why I got 404 except English doc.
   As I haven't checked all pages yet so this is just a guess for now: when you click the URL at the top of the page in doc(except English), it fails in case that the URL format doesn't match https://docs.python.org/3/{some_directory}/{some_page}.html format. If this is true you'll get 404 when you clicked the link from about.html, bugs.html, search.html, py-modindex.html, genindex.html, contents.html, glossary.html, license.html and copyright.html, too.

3. I also clicked the link (of the breadcrumb list) at the bottom of the bugs.html, I don't get the 404 at the all language docs.

Hope it helps.

This is not needed, as this section is only used for local builds. It's replaced by docsbuild scripts to add the switchers.

The referenced bug is fixed in: python/docsbuild-scripts@c23b401.

Thanks for the PR @cocoatomo, and thanks @kanoekakihito for the study of the issue.
