Installer should work in CI (noninteractive) environment

[la-ruby]

It would be nice if this worked in CI environment / github actions:

./bin/rails stimulus_reflex:install
bin/rails aborted!
NoMethodError: undefined method `chomp' for nil (NoMethodError)
      input = Rails.env.test? ? "tmp/app/javascript" : $stdin.gets.chomp
                                                                  ^^^^^^

Hey @la-ruby, thanks for opening this issue!

I was wondering what the use-case for this might be, would you mind to elaborate? I'd be happy to accept a PR to improves this if you want to have a go.
