Remove useless - from help.h on commands with no arguments (#8939)

As far as i can tell it shows up in redis-cli in both HELP, e.g.
`help client list`, and also in the command completion tips, but it is
unclear what it was needed for.
It exists since the very first commit that added this mechanism.
