fix typo

[oversampling]

I am follow along with Youtube video, and I found potential typo in the readme file.

Original

kubectl apply -f rabbits deployment.yaml

Fixed

kubectl apply -n rabbits -f deployment.yaml

In the video, the author use fixed kubectl command in timestamp of 15:27, I believe the author forgot to change in the readme file. The original kubectl will cause error because the deployment.yml should be apply in namespace of rabbits.
