docs/dev/clusteroperator: Fix "he" -> "the" typo

This snuck in with be09d1e (Doc fix for cluster operator creation
step, 2020-10-30, #478).

Re: "or recreate if deleted", the CVO (if it is running) will
eventually get around to recreating the ClusterOperator, as described
in the text added in be09d1e.  But it's still the operator's job to
recreate it if the ClusterOperator is missing, as part of the
"properly update" responsibility.

 ClusterVersionOperator will only deploy files with `.yaml`, `.yml`, or `.json` extensions, like `kubectl create -f DIR`.
 
-**NOTE**: ClusterVersionOperator sweeps the manifests in the release image in alphabetical order, therefore if the ClusterOperator Custom Resource exists before the deployment for the operator that is supposed to report the Custom Resource, ClusterVersionOperator will be stuck waiting and cannot proceed. Also note that he ClusterVersionOperator will pre-create the ClusterOperator resource found in the `/manifests` folder (to provide better support to must-gather operation in case of install or upgrade failure). It remains a responsibility of the respective operator to properly update (or recreate if deleted) the ClusterOperator Custom Resource.
