Add benchmark gem as a dependency.

[willnet]

When using Ruby 3.4 and okcomputer 1.19.0, the following warning appears. Based on the warning message, it seems that to use okcomputer with Ruby 3.5, the benchmark gem needs to be added as a dependency, so I did so.

/home/runner/work/savanna/savanna/vendor/bundle/ruby/3.4.0/gems/okcomputer-1.19.0/lib/ok_computer/check.rb:1: warning: /opt/hostedtoolcache/Ruby/3.4.7/x64/lib/ruby/3.4.0/benchmark.rb was loaded from the standard library, but will no longer be part of the default gems starting from Ruby 3.5.0.
You can add benchmark to your Gemfile or gemspec to silence this warning.
Also please contact the author of okcomputer-1.19.0 to request adding benchmark into its gemspec.

Hi @emmahsax , Could you please review this PR when you have a moment?

Hi. We can probably add benchmark to the Gemfile here:

okcomputer/Gemfile

Lines 35 to 38 in 020168f

	# Gems based on Ruby version
	if ruby_version_float >= 2.5
	gem "mutex_m", "~> 0.3" if rails_version_float < 7.1
	end

Something like this:

# Gems based on Ruby version
if ruby_version_float >= 3.5
  gem "benchmark", "~> 0.5"
  gem "mutex_m", "~> 0.3" if rails_version_float < 7.1
elsif ruby_version_float >= 2.5
  gem "mutex_m", "~> 0.3" if rails_version_float < 7.1
end

The reasoning is that we don't have any other dependencies added to the Gemfile, and doing it this way would add benchmark to every version when that may not be necessary.

Also, please double-check my code, as I didn't test that if condition, but I think it should work just fine.

The gems listed in okcomputer/Gemfile are used only when developing okcomputer. They are not used when you use okcomputer itself. When using it, only the dependencies listed in okcomputer.gemspec are used.

Thank you for that information. I did not know that.
