[SVT][Docs]: Broken link for installing chectl

[DavidG1011]

In our docs, under:
https://www.eclipse.org/codewind/che-installinfo.html#installing-eclipse-che-to-use-with-codewind
we have a link to install chectl:

1. Install the chectl CLI tool. See Installing the chectl management tool. which links to: https://www.eclipse.org/che/docs/che-7/installing-the-chectl-management-tool/ (404)

This page appears to have relocated to: https://www.eclipse.org/che/docs/che-7/using-the-chectl-management-tool/
