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 83e5215 ("async_hooks: use
typed array stack as fast path").
