fix: test crash with mongodb@4.1.1 and node v10

[trentm]

mongodb@4.0.0 dropped support for node v10. However, it wasn't until
v4.1.1 that it failed in usage with the latest node v10.

The failure in GH Actions and Jenkins CI was:

    ...
    # disableInstrumentations
    # individual modules -> @elastic/elasticsearch
    /home/runner/work/apm-agent-nodejs/apm-agent-nodejs/node_modules/whatwg-url/dist/encoding.js:2
    const utf8Encoder = new TextEncoder();
                        ^

    ReferenceError: TextEncoder is not defined
        at Object.<anonymous> (/home/runner/work/apm-agent-nodejs/apm-agent-nodejs/node_modules/whatwg-url/dist/encoding.js:2:21)

• https://nodejs.org/docs/latest-v12.x/api/all.html#globals_textencoder TextEncoder is now on the global object as of node v12 (v11 actually).

• mongodb@4.1.1 was released yesterday:

  "4.1.0": "2021-08-03T21:17:00.887Z",
  "3.6.11": "2021-08-05T16:21:31.587Z",
  "4.1.1": "2021-08-24T20:40:52.030Z"
  

  which includes a major ver bump of "mongodb-connection-string-url"
  mongodb/node-mongodb-native@v4.1.0...v4.1.1#diff-7ae45ad102eab3b6d7e7896acd08c427a9b25b346470d7bc6507b6481575d519L43
  diff

  -    "mongodb-connection-string-url": "^1.0.1"
  +    "mongodb-connection-string-url": "^2.0.0"
  

• which bumped whatwg-url from v8 to v9: mongodb-js/mongodb-connection-string-url@v1.1.2...v2.0.0#diff-7ae45ad102eab3b6d7e7896acd08c427a9b25b346470d7bc6507b6481575d519R60 and dropped support for node v10.

• And that version of whatwg-url assumes TextEncoder is on the global object.
