Suggestion to include go installation in the local monitoring readme.

[bhanvimenghani]

While running local monitoring demo to test my changes i was facing a timeout issue, on debugging figured out its because the script cant run some go commands as go was not installed on my machine which made me think if we could include a statement in the readme asking users to make sure their systems have go installed before going ahead with the demo script.
I was facing the same issue while running vpa demo script as well

@bhanvimenghani The ReadMe indicates that 'go' is prerequisite.
https://github.com/kruize/kruize-demos/blob/main/monitoring/local_monitoring/ReadMe.md

Prerequisites
Ensure you have one of the clusters: kind, minikube, or openShift.
You also require make and a go version > 1.21.

It might be helpful if we can include a function to check on the pre-requisites before proceeding the demo.

Thanks for pointing out! Yes check would be better.
