Reverse plugin mention still present

[outout14]

Following PR #135 which dates from 2019, the mention of the deprecated reverse plugin is still present in the documentation at the URL https://coredns.io/plugins/reverse/

This URL appears at the top of search results when searching for keywords coredns, reverse dns and provides misleading information.

Since this page is not present in the source code of this repository, why is it still accessible?

Nothing in the site links to it. Though, it may still be indexed in search engines from when it was linked to. Or there may be and old blog entry or two that point to the old plugin.

I suppose it's an artifact of how the web server is updated - new files are copied over old files, but deleted files remain.

Don't know if there is an easy way to automatically clean these up, or if it needs to be done manually. (I don't administer the web server)
