fix: unit test cases

[1abhishekpandey]

Description

• After upgrading to the Gradle version 8.2.2, we noticed that unit test cases were failing, as the Gradle has a compatibility issue with an older Java version 11 (which the project was currently dependent upon). This PR bumps the Java version to 17 throughout the project to address that issue.
• Updated the Java version to 17 in GitHub action, as Gradle 8.2.2 is now dependent upon Java version 17.
• After upgrading to Gradle version 8.2.2, we observed that the existing test cases, which utilized Mockito to mock the sealed Message class, began to fail. So, we have resolved the code issue that was causing the unit test to fail in the CentralPluginChainTest class and also used the concrete Message class (instead of mocking the sealed Message class).

Known Issue: A few unit tests are still failing, but this issue is unrelated to the changes made in the Gradle version. The affected module is models. The failing test cases of this module should be addressed in this: https://github.com/rudderlabs/rudder-sdk-android/pull/400/commits/38547b6df0e923e9737f254474f32dbb303f8dfe.

We have decided to use Mockito wherever possible instead of mockk (for the time being). So, I reverted all the changes in the CentralPluginChainTest class and resolved the code issue that was causing the unit test to fail and also used concrete Message class; instead of mocking the sealed Message class.
