Blocker as it is failing builds on che-docs.

The page https://www.eclipse.org/che/docs/next/administration-guide/checluster-custom-resource-fields-reference/ contains a broken link to https://developers.redhat.com/products/codeready-workspaces/overview.

That URL is not published (yet)

As it belongs to the description of a deprecated field, remove the link entirely, and maybe remove the description that is not relevant.

The fix is to happen in the che source code, not in che-docs.
