[BUG] Replace checked in reports-scheduler/src/test/resources/job-scheduler/opensearch-job-scheduler-1.2.3.0-*.zip with a dynamic dependency

[dblock]

Describe the bug

When we increment a version we also need to update job-scheduler by hand.

cd job-scheduler
git checkout 1.2
git pull
./gradlew assemble

rm ../dashboards-reports/reports-scheduler/src/test/resources/job-scheduler/*
cp ./build/distributions/opensearch-job-scheduler-1.2.3.0-SNAPSHOT.zip ../dashboards-reports/reports-scheduler/src/test/resources/job-scheduler/

This random version of job-scheduler built on my machine is not reliable and will hide bugs.

Expected behavior
This shouldn't be needed, replace with a dynamic dependency.

note: to whoever takes this task

reference from job-scheduler README: Add this workaround to make sure that job-schedular plugin is correctly installed during integration tests.

[dblock]

We have to deal with this in every release? How can we get this prioritized?
