docs(logcli): update command reference

[chu121su12]

What this PR does / why we need it:
Updates the outdated shell output in logcli docs

Which issue(s) this PR fixes:

Special notes for your reviewer:
The better PR is to automate ./logcli help and replace the md content. I think I can try on sh but I'm not sure how to integrate with git actions and stuff.

Also this updated help output was formatted with fold since fmt borked some lines.
