Update to run on Nx ~> 0.6

I am using the Ortex lib to do object detection using the Yolov8 model. I need to use Nx.vectorize/2 but it is only available from Nx 0.6 onwards. And Ortex still uses Nx 0.5

Thanks for opening this, bumping the Nx version should be straightforward. I'll update this issue when it's finished.

Updated Nx and other related deps, you should be able to update ortex to 0.1.8 in your project and be good to go!
