CI: Cleanup and enhance to specify platform branch

Fix indentation; setup some more clear variables.

Add a third variable to ensure the proper platform branch is checked
out. This is necessary because otherwise environment deploys get stuck
because the platform directory is in a detached state and then the
environment deploys will not proceed because the branch check
fails. This will fix #8843.
