fix: pin mparticle deps upper bound in higgs-shop sample

[jamesnrokt]

Summary

• Replace 5+ selectors with bounded [5.0,6.0) ranges for com.mparticle:android-core, android-kit-base, and android-rokt-kit in core-sdk-samples/higgs-shop-sample-app/app/build.gradle.kts.

Why

com.mparticle:android-core:6.0.0-rc.1 was published to Maven Central on 2026-05-22. Depending on Gradle's selector parsing, 5+ may resolve to higher than 5.x — including the RC, which removed deprecated symbols. The bounded range removes the ambiguity.

See mParticle/mparticle-android-sdk#710 for the broader incident.

Test plan

• ./gradlew :core-sdk-samples:higgs-shop-sample-app:app:assembleDebug resolves a 5.x set of mparticle artifacts (not 6.0.0-rc.1).
• Sample app still launches.

PR Summary

Low Risk
Sample-app Gradle dependency range change only; no runtime or security-sensitive code paths.

Overview
Pins the Higgs Shop sample app’s mParticle Gradle dependencies so resolution stays on 5.x instead of open-ended 5+ selectors.

android-core, android-kit-base, and android-rokt-kit in core-sdk-samples/higgs-shop-sample-app/app/build.gradle.kts now use [5.0,6.0) ranges, with a short comment pointing at the Maven Central 6.0.0-rc.1 incident and mparticle-android-sdk#710. No application code changes.
