This PR modifies the internal implementation of the Tracer patching for the fetch request module so that it includes the pathname of a request in the segment data.

As reported in the linked issue, the current implementation only records the host name, so a request to https://aws.amazon.com/free would generate a segment similar to this:

{
  "id": "45b22f447784c44f",
  "name": "aws.amazon.com",
  "start_time": 1724108234.18,
  "namespace": "remote",
  "http": {
    "request": {
      "url": "aws.amazon.com",
      "method": "GET"
    },
    "response": {
      "status": 301,
      "content_length": 0
    }
  },
  "end_time": 1724108234.849
}

while it should have generated one like this:

{
  "id": "e861c05fa31a14ab",
  "name": "aws.amazon.com",
  "start_time": 1724108234.856,
  "namespace": "remote",
  "http": {
    "request": {
      "url": "https://aws.amazon.com/free",
      "method": "GET"
    },
    "response": {
      "status": 301,
      "content_length": 0
    }
  },
  "end_time": 1724108235.218
}

Notice how the http.request.url includes both the path and protocol.

The PR also modifies and adds some unit tests to account for the updated logic.
