[Feature request] Allow for easy disablement of either the cypress tests or the script tests via separate enabled: false settings in values

Working on this week's release and while we've agreed to temporarily disable the script tests for gitlab it's proven difficult to do so given the layering from the package's values.yaml up to the umbrella's test-values.yaml.

What I'd like to see working from the umbrella test-values.yaml:

addons.gitlab.values.bbtests.scripts.enabled: false
