[cli] Documentation improvement (#1587)

- Clarify that config.yaml needs to go to CWD
- Add a notice about ente account add (I think it is the second time
someone got confused about this)

Maybe we can also print a notice or the help docs when `ente` is run
without any arguments (just a thought for future changes)
