Use data() instead of begin() in Protocols.cpp (#33476)

* Use data() instead of begin() in Protocols.cpp

The GetProtocolName() function tries to store the result of
std::array<T>::begin() in a raw pointer type, but this no longer works
on some newer versions of clang, since clang now returns an iterator
object. This change fixes this by switching to std::array<T>::data()
instead, which always returns a raw pointer.
