Optimize tooling of kind

[ccremer]

Summary

• Changes the default artifact directory to .work instead of .kind
• Instead of having the kind binary managed in go.mod, we'll use go install instead. go install doesn't required a go.mod, go.sum or tools.go, as opposed to go build or go run. This removes a bunch of boilerplate files.
• Instead of having a fixed version to install, we'll install latest. This should eliminate some Renovate noise, I've rarely seen issues with kind that can be blamed to a certain version. If there is still a version pin required, we can easily do so.
• We'll install the binaries to a local work dir .work/bin by setting our own $GOBIN instead of installing in the user's home dir (usually ~/go/bin), as there are concerns of conflicting versions and binaries used by other projects.
