docs: The same as [`detect`]{@link module:Collections.detect} but runs only a single async operation at a time.

  @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
  @param {AsyncFunction} iteratee - A truth test to apply to each item in `coll`.
  The iteratee must complete with a boolean value as its result.
  Invoked with (item, callback).
  @param {Function} [callback] - A callback which is called as soon as any
  iteratee returns `true`, or after all the `iteratee` functions have finished.
  Result will be the first item in the array that passes the truth test
  (iteratee) or the value `undefined` if none passed. Invoked with
  (err, result).
  @returns a Promise if no callback is passed
