Add Rails 7.1 Support

[JuanVqz]

The railties dependency was blocking compatibility with a new version,
after allowing it should be fine.

Fixes #180

I just tested it in a brand-new app, It worked like a charm 🥳

Needs to update the railties support for 7.1.1

Could not find compatible versions

Because every version of meta_request depends on railties >= 3.0.0, <= 7.1
  and rails >= 7.1.1 depends on railties = 7.1.1,
  every version of meta_request is incompatible with rails >= 7.1.1.
So, because Gemfile depends on rails ~> 7.1.1
  and Gemfile depends on meta_request >= 0,
  version solving has failed

I opened #192 to do this and also add tests, fwiw

[JuanVqz]

Well, it seems like I don't need to update anything, Roguelazer already covered it
