PR Summary

This works to update our middleware to handle redirects for the new benefit finder app located on usa.gov

Related Github Issue

• fixes #1012

Type of change

Detailed Testing steps

Since this turns our application into middleware that redirects routes to new urls, you won't be able to navigate to the pages build without being redirected.

Use the following chart to confirm our redirects are working.
