[EmilNadimanov]

🔧 Type of changes

• new bid adapter
• bid adapter update
• new feature
• new analytics adapter
• new module
• module update
• bugfix
• documentation
• configuration
• dependency update
• tech debt (test coverage, refactorings, etc.)

✨ What's the context?

I assume that these erroneous entries were introduced when porting Go changes to PBS-Java without changing the naming, e.g. inmobi.yaml at PBS-Go. This caused the yaml config to be incorrectly decoded into UsersyncMethodConfigurationProperties.java

🧠 Rationale behind the change

Incorrect configs cause low cookiesync rates, which in return influences Bidder's performance
