Resource handlers fail to handle special characters

[cqlia]

Describe the bug Resource related methods such as Handler.getResourceAsFile fail when special URL characters (like spaces) are used in the resource's path.

To Reproduce Steps to reproduce the behaviour:

1. Create a basic HTTP application
2. Add a new file in the resources with a space in its name
3. Define a new route that responds with a Handler resource method: Handler.fromResource("/resource with spaces")
4. Fetch this route and observe the resulting error - the resource was found by the class but the handler is unable to find it (returns 404 ZIO HTTP Resource /resource with spaces not found)

Expected behaviour The resource should be loaded and sent as the response.

Tested with the latest zio-http version (3.0.0-RC9), and seems to work correctly.

val routes: Routes[Any, Response] = Routes(
    Method.GET / Root / "test" -> Handler
      .fromResource("sample file.txt")
      .mapError(_ => Response.status(Status.NotFound)),
  )

curl -vi -X GET http://localhost:8080/test

> GET / HTTP/1.1
> Host: localhost:9090
> User-Agent: curl/8.6.0
> Accept: */*
> 
< HTTP/1.1 200 OK

Could the leading slash in the resource name be the problem ?
