Update CMake from 3.20.2 to 3.20.4

Summary:
getdeps has been using CMake 3.20.2 since December 2021 (D32805140).

CMake 3.20.2 maps `CMAKE_CXX_STANDARD 20` on MSVC to `/std:c++latest`.

CMake 3.20.4 includes [this change](Kitware/CMake@3aaf1d9), which maps `CMAKE_CXX_STANDARD 20` on newer versions of MSVC to `/std:c++20`.

This change allows OSS builds to build with `CMAKE_CXX_STANDARD 20` without getting dumped into `/std:c++latest`, which may jump to even newer versions than desired.

 ---

This will allow us to build `fbthrift` OSS using C++ 20, and avoid OSS build breakages due to the discrepancy in C++ build standards (C++ 20 internally via Buck, C++ 17 in OSS via CMake) - e.g. D79365997.
