[Bug]: Wrong redirect to version 2 for links without version about docs

[AugustMiller]

These redirects are likely in place due to legacy documentation structures—you can see a complete list of redirections that our provider (Netlify) will perform, in the _redirects file.

I will make sure to update some of these “versionless” pages to point at the equivalent 4.x pages!

Edit: I don't know if within the current system it makes sense to create bulk redirects from the non-versioned URLs (i.e. /docs/elements.html), but know that we are looking into streamlining the structure + routing of the documentation, as a whole!

Missed that file. Sorry for the somehow lazy ticket here. I hope you can work it out. I found:

/docs/updating* https://craftcms.com/docs/2.x/updating.html
/docs/requirements* https://craftcms.com/docs/2.x/requirements.html

But there are some more also to version 3. It just seems that this hasn't been updated for a while. I don't know about the inner workings and where the original links come from so I will not file a PR. Thanks for taking care.
