Improvement required in kubectl get

[Ritikaa96]

What happened:
kubectl get --help states the following even though we can use --namespace to get details for other namespace resources.

Display one or many resources.

 Prints a table of the most important information about the specified resources.
You can filter the list using a label selector and the --selector flag. If the
desired resource type is namespaced you will only see results in your current
namespace unless you pass --all-namespaces.
...

What you expected to happen:
The description should mention --namespace as this can show objects/resources from different namespace as well

How to reproduce it (as minimally and precisely as possible):
Try: kubectl get --help

[Ritikaa96]

/area kubectl
/sig cli

Related to #1432
Would like to contribute this change if the triage get accepted.

I think, this makes sense, because all the other flags in the description is referred as example already.
