Remove errantly added logic to alert on saas feature flag

What does this MR do and why?

Remove errantly added logic to alert on saas feature flag

• errantly added warning that should only be for feature flags
• see !134663 (comment 1611014234) for example of how it is incorrectly alerting and wasn't meant to be brought over when copying feature flag danger - see its intent in !116563 (merged) and how it doesn't apply here.
