Extract URL for description from more OTel span attributes

Description

In OpenTelemetry servlet instrumentation there doesn't seem to be any of the attributes we expect and try to extract the description from.

We should try to extract from attributes that are set in this case.

Example:

  "contexts": {
    "otel": {
      "attributes": {
        "http.request.method": "GET",
        "http.response.status_code": 404,
        "server.address": "some.server.somewhere",
        "url.path": "/manifest.js",
        "url.scheme": "https",
...
      },
