(1.2) `Flipper::TestHelp` initializer raises an error if enabled

[boardfish]

This is with Ruby 3.3, Rails 7.1.2. The solution right now is to set config.flipper.test_help = false in config/application.rb so that the affected code isn't run.

This might be fixed (in a way) on main since the conditional preventing this line from being run has been changed, but in 1.2.0 it would allow this.

I'm not 100% sure the current fix (to check that RSpec responds to configure) is appropriate, since I have rspec-rails installed in this repo and I figure TestHelp would want to configure these hooks. Perhaps there's something to do with load order going on here.

Already fixed by #816, which should get released today.

1.2.1 is out now.
