fix(docker_compose_v2): use correct flag for assume_yes (#1054)

* fix: use correct flag for `assume_yes`

The correct flag is `--y`, not `--yes`.

* refactor(docker_compose_v2): use `-y` instead of `--y` to ensure future compatibility

Maybe they'll change it back to `--yes` sometime, so I'll use the short form that most likely won't change.

* docs(docker_compose_v2): add note about `-y` flag
