Actually drop Rails < 7.0

Pull Request

Summary:
The v3.0.0 changelog mentions that Rails 6.1 support was dropped, which was done by removing it from the CI matrix. However, there's still some code that checks for versions lower than 7.0, and 6.1 is still included on the gemspec.

Description:

This commit addresses that by changing the dependency version, and removing code that isn't needed anymore.

Checklist:

• Code follows the project's coding standards

Thanks @neilvcarvalho 👍

Need to run bundle exec appraisal update as well to update the gemfiles for CI to pass.

@excid3 I pushed an amended commit with the Appraisal updated lockfiles.

Tip: Appraisal recommends not checking in the lockfiles:

When using Appraisal, we recommend you check in the Gemfiles that Appraisal generates within the gemfiles directory, but exclude the lockfiles there (*.gemfile.lock.) The Gemfiles are useful when running your tests against a continuous integration server.

That way, each test matrix entry will resolve the version independently, solving some issues where the same gem is resolved to different versions on the same Rails version depending on the Ruby version. I had issues with factory_bot because of that and following that recommendation worked like a charm.

Appraisal isn't well maintained, so I only use it to generate the Gemfiles. We don't use it for anything else.

2.5.0 was released in July 2023, 3.0.0.rc1 in October 2024 and nothing since.
