Update dependency configuration for JitPack in Kotlin DSL

Previously, JitPack repository was configured using Groovy syntax in the build.gradle file.

Updated configuration:

• Added JitPack repository setup in settings.gradle.kts for plugin management and dependency resolution.
• Confirmed KAndroid dependency declaration in build.gradle.kts using Kotlin DSL.

This change ensures proper integration of JitPack in Kotlin DSL.
