Use NuGet package in C# examples instead of ProjectReference

- Change BallDetection and SimpleClient to use RocketWelder.SDK NuGet package
- Simplify Dockerfiles - no longer need to copy SDK source into build context
- Examples now work as standalone templates for users
- Version: 1.1.34-preview.616c539
