Support Rails 6.1.6.1

This commit does the bare minimum to support Rails 6.1.6.1

Because the `gem` command is no longer reversible, we decided to override the
method by borrowing as much from the [existing
method](https://github.com/rails/rails/blob/04972d9b9ef60796dc8f0917817b5392d61fcf09/railties/lib/rails/generators/actions.rb#L22).
The main difference being that we call `append_file` instead of `gsub_file`, so
that we can preserve reversibility. However, #1066 provides a more elegant
solution.

Closes #1060
