Meta: Check for CMake version in ladybird.sh

CMake reads CMakePresets.json, which is before it reads CMakeLists.txt.
This causes CMake Error: Unrecognized "version" field if the version of
CMake is older than support for presets, or the version field of
presets.

The fix is to check CMake version in ladybird.sh before trying to create
the build directory.
