Support for Ruby 3.3

Add support for Ruby 3.3

Found that rubocop-airbnb requires rubocop 1.32.0 which only supports up to Ruby 3.2, See here.
This is the commit that adds support for 3.3 starting from version 1.46.0.

Summary

• Update rubocop version to support Ruby 3.3
• Constrain rubocop version to be >= 1.61.0
• Fixed some deprecations
• Added Ruby 3.3 to the CI matrix

Test

• Ran tests locally.

It looks like the new workflow for 3.3 is failing because the ruby/setup-ruby snapshot that's being used doesn't have 3.3 support. You'll need to update the following to a newer snapshot of ruby/setup-ruby that has the support:

ruby/.github/workflows/rspec_rubocop.yml

Line 34 in 3e84360

uses: ruby/setup-ruby@ee2113536afb7f793eed4ce60e8d3b26db912da4 # v1.127.0

@Umofomia, just updated the setup-ruby snapshot to v1 let me know whether I should use a specific commit sha or that's OK.

let me know whether I should use a specific commit sha or that's OK.

I'm fine with using @v1, though wondering if @pariser would like to comment here since he originally introduced the specific commit. The ruby/setup-ruby documentation mentions preferring @v1 anyway, though I can see how a specific commit can be more deterministic.

I see it failed for 2.6 because of this breaking change on rubocop-performance
should we remove 2.6 from the tests?

[Umofomia]

It looks like the updates to the dependencies now require Ruby 2.7, so the Ruby 2.6 tests are now failing. We can probably drop support for Ruby 2.6 anyway going forward, so go ahead and remove the 2.6 tests from the matrix:

ruby/.github/workflows/rspec_rubocop.yml

Lines 21 to 22 in bdfad19

	- ruby-version: '2.6'
	bundler-version: latest

I would also update the line here to indicate that the gem itself only supports 2.7 and higher:

ruby/rubocop-airbnb/rubocop-airbnb.gemspec

Line 18 in bdfad19

spec.required_ruby_version = '>= 2.5'

Looks good. Thanks for making the change to add support for Ruby 3.3 to the rubocop-airbnb gem.

[pariser]

This has:

• increased the minimum rubocop version to ~> 1.61 (from ~> 1.32.0)
• dropped support for ruby 2.6
• added support for ruby 3.3

This has not:

• changed any of the rubocop rule configurations

Thank you!
