correct `APP_VERSION` prefix for distro packaging of the cli

[ralphptorres]

two issues discovered while packaging the cli for archlinux aur:

1. using a custom APP_VERSION that doesn't follow cli-drive-* or external-drive-* silently fails with 400 Bad Request on auth/v4/sessions/forks -- no indication of the cause in the error
2. it's unclear which prefix applies to distro packaging of the unmodified cli built from source. external-drive is described as for third-party sdk integrations, cli-drive as the official client. neither description fits a distro repackage cleanly

currently using cli-drive-archlinux but would appreciate confirmation and a note in js/cli/README.md for other packagers :)
