Temporarily disable long running tests

Before this change all the PRs were executing these long running jobs, on avg ~15min each run. But the branch with the changes was not the one being tested, rather just main, therefore wasting time and resource. With the ticket elastic/security-team#9129 we will solve this issue. But in the meanwhile, we are disabling these jobs.
