ci: Set CRYSTALBALL on 2-hourly scheduled pipelines
requested to merge 336524-consider-setting-the-crystalball-variable-only-for-the-2-hour-scheduled-pipelines-via into master
What does this MR do?
It's now possible to set workflow.variables, so we could take advantage of this by setting the CRYSTALBALL variable for the 2-hour scheduled pipelines via workflow.variables instead of setting it for all RSpec jobs regardless of the context and doing the rest of the check in CrystallballEnv.
This MR implements this.
