use subcommands in plugin updaters (#223164)

* update.py: introduce subparsers for plugin updaters

This is preliminary work to help create more powerful plugin updaters.
Namely I would like to be able to "just add" plugins without refreshing
the older ones (helpful when github temporarily removes a user from
github due to automated bot detection).

Also concerning the lua updater, we pin some of the dependencies, and I
would like to be able to unpin the package without editing the csv
(coming in later PRs).

* doc/updaters: update command to update editor plugins

including vim, kakoune and lua packages
