[conan center] advice to use cpp_info.frameworks instead of cpp_info.exe_link_flags

[SSE4]

some old recipes use code like:

self.cpp_info.shared_link_flags.append("-framework CoreAudio")

since conan 1.19, it's better to use just:

self.cpp_info.frameworks.append("CoreAudio")

the hook may advice the new systax over the old one
