Rewrite routes to /.auth** should forward to auth server

Before filing this issue, please ensure you're using the latest CLI by running swa --version and comparing to the latest version on npm.

Are you accessing the CLI from the default port :4280 ?

• No, I am using a different port number (--port) and accessing the CLI from that port
• [ X] Yes, I am accessing the CLI from port :4280

Make sure you are accessing the URL printed in the console when running swa start!

Describe the bug
When adding a route rule to rewrite a route to an auth URL (/.auth**), request instead points to the static web server

{
            "route": "/api/auth",
            "rewrite": "/.auth/me"
}

Log:

remote dev server detected.

• url: /.auth/me
• target: http://localhost:8080
  customUrl: false
  is4xx: false
  remote dev server detected. Proxying request
• url: /.auth/me
• code: 200
  GET http://localhost:8080/.auth/me (proxy)
  Connected to tcp:127.0.0.1:8080 successfully
  http://localhost:8080 validated successfully
  Connected to tcp:localhost:8080 successfully
  getting response from dev server
  GET http://localhost:4280/.auth/me - 404

To Reproduce
Add a route rule that redirects to an auth path.

Expected behavior
Requests for rewritten routes to /.auth** should be forwarded to the auth server, not static server
