Explain in more detail what the hash function does in GlobalScope

Godot 4.3

Currently the documentation only says that it "Returns the integer hash of the passed variable", someone who is new to coding might not understand what it means or where it should or should not be used. I think it should also state what algorithm it uses as it is not stated anywhere.
