GitHub Actions workflow for Ember apps (yarn)

ci-cd.yml

# The workflow template is designed for Ember apps.
#
# It assumes certain dependencies and scripts in package.json. If
# they don't apply to your project, feel free to remove irrelevant
# code in the workflow. These can be inferred from the job name.
