LOG: [libc++] Update the CMake version we use in the CI (#215783)

LLVM is raising the minimum CMake version to 3.31.0. We're currently
using an older version, so we need to upgrade. To make sure things work
with all supported versions this updates to the now oldest supported
version instead of something more recent (which we've done previously).

RFC for updating CMake:

Removed:
