Proof reading ledger-wallet-cli.md guide fix word
Created by: lh1008
I was reading the guide and found the word "you" mistakenly written. Did the changes and made an issue #821 (closed). @el00ruobuob commented and asked me if he would do the PR to correct the word or if I was working on it. I told him I would do the PR. So here it is.

Thank you guys.
