Add how to Setup Merge trains to Merge trains documentation
Problem to solve
Our current Merge Trains documentation doesn't explain how to setup Merge trains.
It says to add only: [merge-requests]
to the jobs - but if a user follows this documentation, any other job that is part of the .gitlab-ci.yml file will not run as part of the merge train. So it actually breaks the previous yml file.
Further details
Proposal
Add a section for setup to the documentation
We need to explicitly say that only: [merge-requests]
needs to be added to every job or be added as a rule on the pipeline
