fix(rust): fix help messages of some CLI commands

[janithjeewantha]

I noticed that the help messages of "ockam tcp-outlet" and "ockam tcp-inlet" display a wrong message for the "show" commands.

Those were corrected by updating the comments used by Clap.

The easiest way to do this is to edit the CONTRIBUTORS.csv file in the github web UI and create a separate Pull Request, this will mark the commit as verified.

Hi @adrianbenavides ,
I think @mrinalwadhwa closed it because I had not accepted the CLA then.
I had to close the CLA PR because I had some troubles and had to delete my fork. So the PR for the CLA acceptance #6290 and another just like this one #6296 had become invalid so I closed them.
Sorry about the mess.

I submitted a new PR shortly for CLA #6307 and @mrinalwadhwa had merged it. So I believe this one can be merged now if possible.

@janithjeewantha I just confirmed with @mrinalwadhwa that it was accidentally closed. Sometimes GitHub does weird stuff when you link issues and PR's between each other. I'll review it ASAP!
