warning hints on mutable methods used with immutable collections

warning hints on mutable methods used with immutable collections

Details

it would be good to have hints showing some warning message("mutable method xyz cannot be used on immutable collection") when immutable collections are used with mutable methods.

example:

var immutableList = List.of(10,20);
      immutableList.add(20);

var immutableList = List.of(10,20);
      immutableList.remove(20);

@mbien as 8519 has been closed earlier with the reasons you have mentioned, i just want to bring up this pr once again and see if this meets the requirements or if still you see if this won't be possible, let me know.
