Remove documentation for removed qHash overload

Browse Source 
QPair is an alias to std::pair in Qt 6, so no need for two qHash functions.
Also remove note and snippet from std::pair overload documentation.

The two functions use different hashing algorithms; due to binary compatibility
constraints, we cannot change the QPair algorithm to match the std::pair one before Qt 6.
