fix: docops-551 extra backslashes in KIC docs

[Jcahilltorre]

Proposed changes

Remove extra \ appearing in two KIC documents at:
https://docs.nginx.com/nginx-ingress-controller/configuration/virtualserver-and-virtualserverroute-resources/
and
https://docs.nginx.com/nginx-ingress-controller/configuration/global-configuration/configmap-resource/

I think one more place is missing, here's a patch to fix:

Other than that, LGTM!
