fix: instrumentation of @aws-sdk/client-* v3.723.0 and later now works

[trentm]

v3.723.0 and later of some aws-sdk-js v3 clients updated to use @smithy/smithy-client@4
which is part of what is instrumented.

---

TAV tests for client-s3, client-sns, and client-sqs started failing with the 3.723.0 version released earlier today.
E.g.: https://github.com/elastic/apm-agent-nodejs/actions/runs/12641762762/job/35224835256

$ npm info @aws-sdk/client-s3 time
...
  '3.716.0': '2024-12-19T20:06:49.540Z',
  '3.717.0': '2024-12-20T19:58:02.159Z',
  '3.721.0': '2025-01-02T20:07:43.217Z',
  '3.722.0': '2025-01-03T19:56:43.048Z',
  '3.723.0': '2025-01-06T20:58:42.380Z'

The interesting part of the diff of those versions:

-        "@smithy/core": "^2.5.5",
-        "@smithy/smithy-client": "^3.5.1",
+        "@smithy/core": "^3.0.0",
+        "@smithy/smithy-client": "^4.0.0",

       "engines": {
-        "node": ">=16.0.0"
+        "node": ">=18.0.0"
       }
