feat: Update the Golang Dockerfilegenerator transformer to support multi-arch build

[Akash-Nayak]

Changed the base image to registry.access.redhat.com/ubi8/go-toolset for building the app with multi-arch support. The base image supports amd64/arm64/ppc64le/s390x.

I was successfully able to build the multi-arch image for amd64, arm64 and ppc64le (Power), but for s390x (Z) arch the build gets stuck at RUN go build -o ./bin/golang.
