fix: remove node-abort-controller polyfill, breaking Node 24 compatibility (#927)

Node 24 tightened validation in events.setMaxListeners() to require true
EventEmitter/EventTarget instances. The node-abort-controller polyfill's
AbortSignal is a plain object, causing ERR_INVALID_ARG_TYPE crashes during
aio app init. The polyfill was added for Node <=16.13 compat and is no
longer needed since engines.node is >=20.

Fixes ACNA-4621
