Pull Request Overview

This PR simplifies the documentation link in the InformationPopup component by replacing language-specific URL logic with a single language-agnostic URL. The ydb.tech website now handles language detection automatically, making the client-side language routing unnecessary.

• Removed the getDocumentationLink() function that dynamically generated language-specific URLs
• Removed unused imports for settingsManager and SETTING_KEYS
• Replaced dynamic URL generation with a static https://ydb.tech/docs URL
