fix(help): Prefer short version over long version

Browse source 
When we got #3193, we decided in #3196 that `--help` will give a summary
for other commands (`subcmd --help` in this case) but not show the long
version of the output for that other command.

Now with #3215, I think the case is similar for `--help` not showing the
long version but instead preferring the short version and encouraging
people to run `--version`.

Originally. clap only showed the short version or nothing.  This was
changed in #2369 without fanfare to prefer the long version over short.
Now are we preferring short version over the long version always, just
like all other help.

Fixes #3215
