update resource builder error message to be more clear

release-note-none

The error message given by command line `kubectl get` is sometimes of no help / not clear on what must be corrected, e.g.：
`kubectl get pod pod/database-1-i10b9`
error: when passing arguments in resource/name form, all arguments must include the resource 

##### Steps to Reproduce:
1. Run command "$ kubectl get pod pod/database-1-i10b9"  

##### Actual Result:
Get unfriendly error message which is of no help:
"error: when passing arguments in resource/name form, all arguments must include the resource"

##### Expected Result:
Error message should recommend end user to run this cli in good grammar: "$ kubectl get pod database-1-i10b9" or "$ kubectl get pod/database-1-i10b9"

##### Before
"error: when passing arguments in resource/name form, all arguments must include the resource"

##### After
"error: there is no need to specify a resource type as a separate argument when passing arguments in resource/name form (e.g. `kubectl get resource/<resource_name>` instead of `kubectl get resource resource/<resource_name>`"
