Fix Experiments evaluation of new dep dependencies

[grvillic]

Context

As we were evaluating the .NET experiment for new detector, we noticed a bug in our experimental diffing evaluation. If a new dev dependency is introduced that is not reported in control group, it should still be reported as a dev dependency. As of now, that component only gets added to the AddedIds but it never gets flagged as dev dependency.

👋 Hi! It looks like you modified some files in the Detectors folder.
You may need to bump the detector versions if any of the following scenarios apply:

• The detector detects more or fewer components than before
• The detector generates different parent/child graph relationships than before
• The detector generates different devDependencies values than before

If none of the above scenarios apply, feel free to ignore this comment 🙂
