Mismatched service name in examples page
Problem to solve
The https://docs.gitlab.com/ee/ci/examples/test-and-deploy-ruby-application-to-heroku.html#create-runner page mentions a PostgreSQL but the example script mentions MySQL. This was introduced in gitlab-runner!2036 (merged). Previously the service installed was wrongfully named latest
.
Further details
Proposal
Make the following change:
-name = "mysql:latest"
+name = "postgres:latest"
