fix(cli): drop the deleted apps/cloud path from the publish help example (#15390)

`os package publish --help` printed its local-dev example as:

    $ OS_CLOUD_URL=http://localhost:4000 os package publish    # local dev (apps/cloud)

`apps/cloud` was deleted from this repository -- the reference cloud host
now lives in `objectstack-ai/cloud` -- so the parenthetical told a user to
run something against a directory absent from the tree they cloned. Unlike
the source comments swept alongside it, this string is user-facing output:
`static override examples` is printed verbatim by oclif under EXAMPLES.

The parenthetical is dropped rather than re-pointed at the other repo. The
example teaches that `OS_CLOUD_URL` overrides the control-plane URL, which
the `--server` flag documents a few lines above in the same output; which
directory happens to serve `localhost:4000` was never part of that, and a
`--help` reader is not looking for a file in a monorepo. Two things on the
tree already spell it that way: `content/docs/deployment/cli.mdx` publishes
this same example with no directory, and the sibling `os plugin publish`
gives the identical env-override example with no trailing comment at all.

No behaviour moves: no flag, argument, default or exit code changes.
