We're seeing multiple build failures with CMake 4.0 on macOS: e.g. SwiftPM bootstrapping issues. `build-script` will always build a fixed version of CMake that's known to work, if preinstalled one is not found. Let's reduce the chances for confusion by not preinstalling CMake for those who use `Brewfile`.

Brew allows selecting a specific version doesn't it? Can we just pin it?

It does not, at least for CMake only latest version is provided:
❯ brew install cmake@3.31
Warning: No available formula with the name "cmake@3.31". Did you mean cmake?
==> Searching for similarly named formulae and casks...
==> Formulae
cmake ✔
To install cmake ✔, run:
brew install cmake ✔
❯ brew install cmake@3.31.8
Warning: No available formula with the name "cmake@3.31.8".
==> Searching for similarly named formulae and casks...
Error: No formulae or casks found for cmake@3.31.8.
❯ brew install cmake@3
Warning: No available formula with the name "cmake@3". Did you mean cmake, cake or make?

Would be nice to get this working, but better to not be confusing for now 👍
