Please bump commander dependency to avoid abbrev warning on Ruby 3.3

Is your feature request related to a problem? Please describe.

Parlour transitively depends on a version of highline that emits a warning on Ruby 3.3.

The latest release of parlour depends on commander ~> 4.5, which depends on highline ~> 2.0.0, which emits a warning on Ruby 3.3 when required:

/Users/owenstephens/.rbenv/versions/3.3.0/lib/ruby/gems/3.3.0/gems/highline-2.0.3/lib/highline.rb:17: warning: abbrev was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add abbrev to your Gemfile or gemspec. Also contact author of highline-2.0.3 to add abbrev into its gemspec.

Describe the solution you'd like

Please change the commander dependency to ~> 5.0 to release a transitive dependency on highline so that the fix in JEG2/highline#268 can be included (which was released in highline 3.0.1)

The commander changelog for 5.0.0 mentions that moving to 5.0 will drop support for Ruby < 3 and update the highline dependency:

https://github.com/commander-rb/commander/blob/98dee54912730397d06eca9132dbfd2ec3bbd4b0/History.rdoc#L1-L3

Describe alternatives you've considered

I think the requested change is reasonable since Ruby 2.7 (the last that is < 3) has been EOL for over a year

Additional context

To reproduce, use Ruby 3.3.0, and a simple Gemfile that includes:

gem "parlour", "= 8.1.0"

then a warning will be printed as follows when requiring highline:

$ bundle exec ruby -rhighline -e 'puts "hello world from Ruby #{RUBY_VERSION}"'
/Users/owenstephens/.rbenv/versions/3.3.0/lib/ruby/gems/3.3.0/gems/highline-2.0.3/lib/highline.rb:17: warning: abbrev was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add abbrev to your Gemfile or gemspec. Also contact author of highline-2.0.3 to add abbrev into its gemspec.
hello world from Ruby 3.3.0

@owst, @hlascelles - Apologies for the long delay. This is now released as Parlour 9.0.0, and removes the warning on my end!
