Adds Ruby 3.3 to CI

[berkos]

This PR adds Ruby 3.3 in the CI matrix.

It excludes rubies that are incompatible with Rails 7.2

Because every version of rails depends on Ruby >= 3.1.0
  and Gemfile-rails-main depends on rails >= 0,
  Ruby >= 3.1.0 is required.

Yes please!

Thanks. We can add the Ruby version to the build, but need to wait a bit until 7.2 is released to add a custom 7.1 gemfile to test against.

[carlosantoniodasilva]

7.1 is tested from our main Gemfile, we generally don't add a new / custom one until 7.2 is released. (that's when the Gemfile moves to test the current 7.2, and we add the previous as a custom Gemfile to continue testing it)

Hi, thanks for the review!
ah yes, I missed that main Gemfile is also in the matrix.
The updated commit should address it c80026d
