GHA Kogito Runtimes: I hit 2 issues and filed them.

Possible flaky PojoServiceIT in kogito-quarkus-serverless-workflow-integration-test
#3645

Possible reproducible build issue in integration-tests-springboot-processes-filesystem
#3646

I believe merging this PR without fixing the above 2 issues is justified, because this PR disables failing tests so it will contribute to other issues' debugging/investigation.
