doc: fix documentation for `MODULE_NOT_FOUND` and `ERR_MODULE_NOT_FOUND` by aduh95 · Pull Request #41645 · nodejs/node

aduh95 · 2022-01-22T10:41:58Z

ERR_MODULE_NOT_FOUND was still marked as experimental, probably an oversight from #35781.
ERR_MODULE_NOT_FOUND is thrown wether the target specifier would be an ES module or not (we cannot really know the format of a file that doesn't exist anyway).
I've added a note regarding which module loader is involved (sorry @GeoffreyBooth), which is unfortunate but I didn't know how to explain the difference otherwise.
