Fix implicit dependencies between tasks

[sohyun-ku]

Integration Test was disabled when run scavenger-agent-java:build that triggered by PR builder.
To solove this problem, we can use 'mustRunAfter' to specify the order between 'jar' and 'integrationTest' tasks.

Execution optimizations have been disabled for task ':scavenger-agent-java:integrationTest' to ensure correctness due to the following reasons:

• Gradle detected a problem with the following location: '/home/runner/work/scavenger/scavenger/scavenger-agent-java/build/libs/scavenger-agent-java-1.1.1-SNAPSHOT.jar'. Reason: Task ':scavenger-agent-java:integrationTest' uses this output of task ':scavenger-agent-java:jar' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed. Please refer to https://docs.gradle.org/7.6.1/userguide/validation_problems.html#implicit_dependency for more details about this problem.

I think there was an issue with enabling jar tasks in #91.
Thanks you 😄 , it would have remained a serious bug if you hadn't checked the result of the action.

Since the integration test passed in this PR, can we assume that the Support JDK 21 #101 PR is okay?

Of course, this PR is after e944d38 commit :)
