* fix(backend,remix): Tweak ClerkRequest initialization to work-around edge-runtime and undici limitations

The usual way to duplicate a request object is to
pass the original request object to the Request constructor
both as the `input` and `init` parameters, eg: super(req, req)
However, this fails in certain environments like Vercel Edge Runtime
when a framework like Remix polyfills the global Request object.
This happens because `undici` performs the following instanceof check
which, instead of testing against the global Request object, tests against
the Request class defined in the same file (local Request class).
