build: replace make setup with go run and version suffixes

What does this MR do?

Go run now accepts arguments with version suffixes (for example, go run example.com/cmd@v1.0.0).

See https://tip.golang.org/doc/go1.17

Previously, we were using a go.mod file to handle versioning of dev tools but we can streamline the process and drop the old workaround now that Pages is on Go 1.17.
