Update Room to 2.7.0 for Kotlin 2.1.0 compatibility

Room 2.6.1 doesn't support Kotlin 2.1.0 metadata. Updated to Room 2.7.0 which includes support for Kotlin 2.0+ metadata versions. This fixes the KAPT error: "Provided Metadata instance has version 2.1.0, while maximum supported version is 2.0.0".
