Dockerfile repo updates

I need a slight modification to the changes made previously where changes in the mariadb server repo updates the repo with the Dockerfiles ( https://github.com/mariadb-corporation/mariadb-server-docker ) by pushing a “version” file. Instead of pushing the version file to the master branch, I need it to push to branches 10.1, 10.2, or 10.3 depending on the version. I’ve kept the folder names the same. The folder name is the same as the branch and major version name: 10.1, 10.2, and 10.3.
