`go install` should be used instead of `go get` to install binaries

[jayesh-srivastava]

From Go 1.17, installing executables with go get is deprecated. go install may be used instead.
In Go 1.18, go get will no longer build packages; it will only be used to add, update, or remove dependencies in go.mod.

Ref. - (https://go.dev/doc/go-get-install-deprecation)

We should stop using go get to install hack/tools and instead rely on go install.
