Patch global.json to 7.0.100 for macOS

  - `dotnet format` is broken on macOS with .NET SDK 7.0.101 (mimicking craigktreasure/Treasure.Utils#31). So, we're installing 7.0.100 in addition to the latest and patching the `global.json` file at build time on macOS to prevent rolling forward to the latest SDK version. This means we'll use the latest on Windows and Linux, but macOS will be pinned o 7.0.100 for now until it's fixed.
