[Update] Linode Cloud Manager Security Controls
Removing alias that is the same as the guide's directory path

Reported by Linode support:
This guide is currently redirecting to itself in an infinite loop:
https://www.linode.com/docs/security/linode-manager-security-controls/

I noticed that one of the aliases on the guide is security/linode-manager-security-controls/, which is the same as that guide's path. I logged into the production server and saw that Hugo had rendered a redirect page at that URL, instead of a normal page with content.

Proposed fix is to remove that alias. Some other weird things I noticed:

• The last time we touched this line in the file was ten months ago, and we didn't even add this problematic alias at that time: https://github.com/linode/docs/pull/2414/files
• The problem isn't appearing for me when running on the dev server on my Mac (Hugo version 0.52), nor does it appear in the Netlify preview from [Fix] Linode Cloud Manager Security Controls #2414
• I am pretty sure that this guide has worked for the last ten months, so I'm not sure why it came up now.
