Make binaries avaiable

[luebken]

I would like to write a guide that leverages k8scr to make Crossplane fully offline available. With the current setup users would need to clone this repo and run make build. I would like to simplify the setup that it doesn't involve any go build or make build. A simple script to curl would be fine.

@luebken apologies for the long delay here! We now have initial CI in place and artifacts are being uploaded alongside the worflow runs (example: https://github.com/hasheddan/k8scr/actions/runs/2034352096). We should have a first release available soon with binaries for common platforms 👍🏻
