Actually drop Rails < 7.0

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.

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