Upgrade Kotlin to 2.0.21 in Stripe-dependent modules

[sg-jsonjuliane]

PR Context

• Type: Refactor
• Issue Link: Redmine Issue
• Risk Factor: Medium - Kotlin version upgrade from 1.8.20 to 2.0.21 affects compilation and type checking. Room upgrade from 2.5.1 to 2.6.1 required for kapt compatibility. Changes are minimal and focused on version updates and kapt configuration.

Changes

Upgrade Kotlin to 2.0.21 and update Room to 2.6.1 for compatibility with kapt and Kotlin 2.0.

• Updated Kotlin version from 1.8.20 to 2.0.21 in dependencies.gradle
• Updated Room version from 2.5.1 to 2.6.1 in dependencies.gradle (required for kapt compatibility with Kotlin 2.0)
• Updated Kotlin version in build.gradle to 2.0.21
• Added kapt configuration in TripKitData/build.gradle for Kotlin 2.0 compatibility (useBuildCache, mapDiagnosticLocations)

The changes look good. I also tested payments on both the Catch a Ride and ODIN WLs, and the payments went through successfully. Thanks.
