formatted_flags always prints all flags #16418
Description
The logic in Signature::formatted_flags make it seem that the intent was to truncate more than 10 flags, but it always prints all of them.

Example:
~> ulimit --doesnt-exist
Error: nu::parser::unknown_flag
× The `ulimit` command doesn't have flag `doesnt-exist`.

help: Some available flags: --help(-h), --soft(-S), --hard(-H), --all(-a), --core-size(-c), --data-size(-d), --nice(-e), --file-size(-f), --pending-signals(-i),
--lock-size(-l), --resident-set-size(-m), --file-descriptor-count(-n), --queue-size(-q), --realtime-priority(-r), --stack-size(-s), --cpu-time(-t), --process-
count(-u), --virtual-memory-size(-v), --file-locks(-x), --realtime-maxtime(-y)... Use `--help` for a full list of flags and more information.Currently this method is only used by the parser. I wonder if it would be a good idea to use did_you_mean instead?
