Documentation: Remove redundancy in CodingStyle.md

This is a fairly small change; removed the statement "Pointer and
reference types in C++ code" as it does not provide any additional

reading into the "Pointers and References" section. It seems
unnecessary and redundant given the sentence adjacent to it.
