local_working_copy: fix warnings ending up on stdout

As suggested by @crackcomm on discord, use eprintln!() to print warnings to avoid messing up template output, e.g.: jj --no-pager --ignore-working-copy show --tool true -T change_id -r rv... rv...ignoring git submodule at "some/submodule" Signed-off-by: Tim Janik <[email protected]>
