Build fails to find "GO"

[jjacob27]

When I tried this command
docker build -t plugin-build-tools:latest .
as mentioned in the documentation, it failed to install golang in the image.

I had to modify the Dockerfile to include the two lines before the RUN yum install -y git make golang
RUN rpm --import https://mirror.go-repo.io/centos/RPM-GPG-KEY-GO-REPO
RUN curl -s https://mirror.go-repo.io/centos/go-repo.repo | tee /etc/yum.repos.d/go-repo.repo

Hopefully you can review this and add this step to the main readme
