Fix incorrect output of example in ACL DRYRUN

[enjoy-binbin]

In redis/redis#10405, we will check arity first, so the example
output is wrong. And in redis/redis#11160, we changed the text.

127.0.0.1:6379> ACL DRYRUN VIRGINIA GET foo bar
(error) ERR wrong number of arguments for 'get' command

127.0.0.1:6379> ACL DRYRUN VIRGINIA GET foo
"User VIRGINIA has no permissions to run the 'get' command"
