[icanerdogan]

🎯 Goal

To convert the build.gradle files to build.gradle.kts for better type safety, auto-completion, and maintainability within the Stream Chat Android project.

🛠 Implementation Details

• Replaced all existing build.gradle files with their Kotlin DSL equivalents (build.gradle.kts).
• Updated build script dependencies and configurations to align with Kotlin DSL syntax.
• Ensured compatibility with the current project structure and dependencies.
• Verified that all Gradle tasks (e.g., build, test, lint) work seamlessly after the migration.
