fix(android): allow older Kotlin compilers with ads SDK 25.4

[floze-the-genius]

Description

Google Mobile Ads 25.3+ embeds Kotlin 2.3 metadata even though this module only consumes its public Java API. That makes the library fail to compile in Expo and React Native projects still using Kotlin 2.1.x.

Configure only this library's KotlinCompile tasks to skip the dependency metadata version check. This preserves the Android AgeRestrictedTreatment API added with the newer SDK without forcing every consumer module to upgrade to Kotlin 2.3.

Test Plan

• Reproduced the failure in a focused Gradle harness using Kotlin 2.1.0 and the exact play-services-ads:25.4.0 AAR classes.
• Verified the same harness compiles after applying the scoped -Xskip-metadata-version-check configuration in Groovy.
• yarn tests:jest --runInBand (7 suites passed, 79 tests passed)
• yarn tsc:compile
• yarn lint

A full Android example assemble was not run locally because this machine has no accepted Android SDK installation; the repository Android CI remains the end-to-end build check.
