lib: update executionAsyncId/triggerAsyncId comment
This commit updates the comment referring to the executionAsyncId/triggerAsyncId pair being stored in a std::stack.
It looks like this was changed from std::stack to AliasedFloat64Array in Commit 83e5215a ("async_hooks: use typed array stack as fast path").
