### What changes were proposed in this pull request? This PR aims to upgrade `Mockito` to 5.24.0. Since `mockito-core` 5.24.0 declares the same dependencies as 5.23.0 (`byte-buddy` 1.17.7, `byte-buddy-agent` 1.17.7, and `objenesis` 3.3), only the `org.mockito:mockito-core` entry of `gradle/verification-metadata.xml` is changed. ### Why are the changes needed? To bring the latest bug fixes. - https://github.com/mockito/mockito/releases/tag/v5.24.0 (2026-09-23) - Fix data race in `InvocationContainerImpl.invocationForStubbing` (mockito/mockito#3819) - Fix non-deterministic `AssertionError` when using `MockMakers.SUBCLASS` (mockito/mockito#3795) - Fix `clearInlineMocks` not de-registering singleton mocks (mockito/mockito#3829) - Preserve method parameters when clearing inline mocks (mockito/mockito#3847) ### Does this PR introduce _any_ user-facing change? No. `Mockito` is a test-only dependency. ### How was this patch tested? Pass the CIs. ### Was this patch authored or co-authored using generative AI tooling?
