test: test with Node.js 22 (#2350)

Also:
- Fix a flaky test failure with socket.io@4.7.4 and node 18, 20, and 22.
  With those Node.js versions the 'traceReserved:true on is instrumented' test
  case in "socket.io.test.ts" would sometimes hang with node 18 and
  (almost?) always hang with node 20 and 22.
- test fix for socket.io@2.x and Node.js 22.
  This is a fix/workaround based on a hunch from the other socket.io.test.ts fix.
