CLI docs: cloud-init devel hotplug-hook <subcommand> --help is empty or lacks mention of required --subsystem param.

Bug report

No parameter information about the required --subsystem option is provided by cloud-init devel hotplug-hook query --help or handle --help

root@test-n:~# cloud-init devel hotplug-hook  query -h
usage: /usr/bin/cloud-init devel hotplug-hook query [-h]

options:
  -h, --help  show this help message and exit

root@test-n:~# cloud-init devel hotplug-hook  handle --help
usage: /usr/bin/cloud-init devel hotplug-hook handle [-h] -d PATH -u {add,remove}

options:
  -h, --help            show this help message and exit
  -d PATH, --devpath PATH
                        Sysfs path to hotplugged device
  -u {add,remove}, --udevaction {add,remove}
                        Specify action to take.

Expected representation of the required --subsystem parameter in both cases.

@blackboxsw are you saying that this was introduced in the dhcpcd PR? That is surprising, since that PR doesn't touch any files in the cloudinit/cmd/ subdirectory.

No, I was just representing that this bug still affects tip of main at the commit https://github.com/canonical/cloud-init/commit/21b2b6e4423b0fec325b32042c05ef4274cdd301. This is probably confusing to track a commit in upstream main. We can redact the commit hash if you think that's preferable because any live bug should be considered something as something that affects tip of main.
