Nested routes serve routes on all nested paths

[amumurst]

Describe the bug
The feature of nesting routes is exposing paths on both the original path, and on the nested path.
https://zio.dev/zio-http/reference/routing/routes#nested-routes

To Reproduce
I found it by curl-ing my app, but here is a reproducer using both the direct request syntax and calling the server directly

//> using dep "dev.zio::zio-http:3.0.1"
import zio.*
import zio.http.*
import zio.http.codec.PathCodec

object HelloWorld extends ZIOAppDefault:
  val routed = PathCodec.literal("foo") / Routes(
    Method.GET / "hello" -> handler(Response.text("World"))
  )
  val hello = Request.get("http://localhost:8080/hello")
  val fooHello = Request.get("http://localhost:8080/foo/hello")
  override def run = {
    for {
      res1 <- routed.runZIO(hello).debug //Gives OK
      res2 <- routed.runZIO(fooHello).debug //Gives OK
      p <- Server.serve(routed).forkDaemon
      res3 <- Client.batched(hello).debug //Gives OK
      res4 <- Client.batched(fooHello).debug //Gives OK
      _ <- p.interrupt
    } yield ()
  }.provide(Server.default ++ Client.default)

Expected behaviour
Only the requests to fooHello respond with 200 OK, with the requests to hello giving 404.
