Do not join cookies with new like if they weren't before
Add `Rack::Headers` wrapping to middleware to prevent header manipulation issues. Added a test to verify cookies remain as an array when flagged if already in array format.

Pull Request Overview
This PR fixes compatibility with Rack 3 by updating the handling of cookie headers, ensuring that cookies passed as either an array or a newline-delimited string are correctly processed.
- Update test expectations to use newline-delimited strings for cookie headers
- Modify middleware to handle cookies based on their original type (array vs. string)
- Add a new test to verify that an array remains an array after processing

spec/lib/secure_headers/middleware_spec.rb:86
- [nitpick] Ensure that this test also covers possible edge cases, such as improper formatting or unexpected delimiters in the cookie header, to provide comprehensive validation of the splitting logic.
cookie_middleware = Middleware.new(lambda { |env| [200, env.merge("Set-Cookie" => "_session=foobar\n_guest=true"), "app"] })
