test: stop using the obsolete AsyncHooksContextManager in tests

[trentm]

Since support for Node.js <14.8.0 was dropped, the modern
AsyncLocalStorageContextManager can always be used. This was done
for runtime code in open-telemetry/opentelemetry-js#4341
This PR does this for tests that were explicitly setting a
context manager.

Review note: the switch to AsyncLocalStorage for context management results in some spans getting net.peer.{name,port} being applied where it was not before. Presumably this is because AsyncLocalStorage is doing a better job following the async-context and this code block now gets triggered.
