Update conan.cmake to support actual version of Visual Studio 2022

[giovaorama]

As reported in https://cmake.org/cmake/help/latest/variable/MSVC_VERSION.html the maximum value for the visual studio 2022 is now less than 1950 not 1940. 1940 is the release 17.10

Hi @giovaorama

Thanks for your contribution. This has already been fixed and merged to develop branch in #643, marking this as a duplicate.

A release hasn't been done, because cmake-conan for 1.X is now legacy, the default and maintained one is Conan 2 using the new CMake dependency providers.
