[btalayeminaei]

• Add Ruby 3.3 to CI matrix
• Add Ruby 3.4 to CI matrix
• Add Active Support 8 to CI matrix

CI is green on my fork btalayeminaei#1

Active Support 6 relies on libraries (e.g. base64, bigdecimal, etc.) that are no longer part of the default gems in Ruby 3.4. Since business_time does not appear to rely on these libraries, I did not update the gemspec and chose to test Ruby 3.4 only with Active Support 7+. Please let me know if I should go a different route. Thanks!

/versions/3.4.1/lib/ruby/gems/3.4.0/gems/activesupport-6.1.7.10/lib/active_support/xml_mini.rb:5: warning: bigdecimal was loaded from the standard library, but is not part of the default gems starting from Ruby 3.4.0.
You can add bigdecimal to your Gemfile or gemspec to silence this warning.

[SUGGESTION] Let's limit the core matrix to the supported ruby versions and a subset of the older ruby and activesupport version combinations to the include.

Suggested change

	ruby: [2.7, "3.0", 3.1, 3.2, 3.3, 3.4]
	ruby: ["3.2", "3.3", "3.4"]

[rmm5t]

[SUGGESTION]

Suggested change

	- { ruby: "2.7", gemfile: "active_support_6", bundler: "1" }
	- { ruby: "3.0", gemfile: "active_support_6", bundler: "1" }
	- { ruby: "3.1", gemfile: "active_support_6", bundler: "1" }
	- { ruby: "3.2", gemfile: "active_support_6", bundler: "1" }
	- { ruby: "3.3", gemfile: "active_support_6", bundler: "1" }
	- { ruby: "2.7", gemfile: "active_support_6" }
	- { ruby: "3.0", gemfile: "active_support_7" }
	- { ruby: "3.1", gemfile: "active_support_7" }

[rmm5t]

[SUGGESTION] Let's also add an active_support_8 here with a new gemfile.

[rmm5t]

[PLEASE REMOVE] bundler: "1" from each of these. They can run under the latest (default) version of bundler for each version of ruby.

Got it. Thanks

Looks good!
