Update docker build instructions #104
Description
The docker build instructions currently state to run:
docker run --volume=$(pwd):/home/circleci/project olback/rust-gtk-linux cargo build --release
That docker container is out of date and listed as deprecated on dockerhub besides. The app builds correctly with the new container:
docker run --volume=$(pwd):/home/circleci/project olback/rust-linux-gtk cargo build --release
