chore: test adjustments

[daniel-sanche]

• We recently added sandboxctl test to run tests against a live sandbox environment, but it wasn't working for the ratingservice tests. This fixes that
• added a dependency to the make-release release pipeline, so it will run steps in sequence instead of parallel (add dependency on release pipeline jobs #943)
• removed quotes from workflow custom image trigger, since the trigger wasn't firing and removing quotes seems to be better in line with the spec
