cli/docs/reference/commandline/service_update.md
Aaron Lehmann 012fa2fd1b Update --update-parallelism docs 
Update documentation to account for the changes in #24952.

docs/swarm/swarm-tutorial/rolling-update.md doesn't need any changes,
but the CLI reference pages should show the current help text.
drain-node.md no longer needs to specify --update-parallelism 1 in its
example.
