Add Ruby 3.3 and 3.4 to CI.

Hello!

I'm fully aware of this project is archived and it is suggested to migrate to pro version. This is just to ensure original knapsack gem latest version work also on modern Rubies. There is no need for release or any other maintenance.

Hi @simi, I'd like to understand better what prompted you to open this PR.

Are you a user of this gem? Have you considered using Knapsack Pro?

We do not trigger CI builds on Github Actions. Would you be willing to share how having this change merged would help with your use-case?

Hello @3v0k4, I'm not Knapsack user. But I'm interested in ensuring popular gems are covered on CI with modern Rubies to get public proof those gems are compatible with them. knapsack gem still gets around ~8M downloads per month. Current master branch is code-wise same as last release (4.0.0). By approving workflow approval, we can check if gem is still compatible with Ruby 3.3 and 3.4 and by merging it will be better visible since last commit in repo will be tested against those modern Rubies.

There is no additional work needed. No need to release new gem or do any other release. It is quite similar to #120, but with newer Rubies.

@simi thanks for the context. And thanks for taking care of keeping the Ruby ecosystem healthy!

Would you be willing to move racc into the gemspec together with the other dev dependencies?

I'd be happy to merge this.

@3v0k4 Done. I wasn't sure where to put it, since it is not direct dependency of knapsack, this should be fixed in gherkin-ruby gem, but that is without update for 11 years and is abandoned by users also.

@simi Thanks. Keep up the good work!
