`delete-context` does not delete the context

[rmntrvn]

Hello.

I have a file ~/.kube/config which contains many kubernetes contexts.

When I run the command s delete-context <context name from the list>, the command is executed and prints the message:

delete-context some-context-name [some-context-name] <nil>

but the context is not deleted from the list.

I checked the code and I think this part is missing. It would be great to have that
