chore: use go install instead of depcreated go get

[chewong]

Signed-off-by: Ernest Wong chuwon@microsoft.com

Reason for Change:

Replace go getwith go install when installing tool binaries.

go get: installing executables with 'go get' in module mode is deprecated.
	To adjust and download dependencies of the current module, use 'go get -d'.
	To install using requirements of the current module, use 'go install'.
	To install ignoring the current module, use 'go install' with a version,
	like 'go install example.com/cmd@latest'.
	For more information, see https://golang.org/doc/go-get-install-deprecation
	or run 'go help get' or 'go help install'.

Notes for Reviewers:

Go install does not work with kustomize for now:

go install: github.com/kubernetes-sigs/kustomize/kustomize/v4@v4.1.2 (in github.com/kubernetes-sigs/kustomize/kustomize/v4@v4.1.2):
        The go.mod file for the module providing named packages contains one or
        more exclude directives. It must not contain directives that would cause
        it to be interpreted differently than if it were the main module.

Switched to downloading the tarball.
