* compose: make `project directory` explicit

See https://github.com/docker/compose/issues/8347 .
Some users assume that `project directory` is the directory which has `docker-compose.yaml`.
But this is not true (at least for now) when you execute `docker-compose` in sub directory.
This PR makes it clear.

* fix a typo and made style updates
