ci: Add DuplicatedCode Qodana check (#5850)

Adds Qodana check for duplicated code, which show up in Qodana as Moderate level changes (lowest level)

FYI: We may have to YOLO merge this file in to get picked up in CI: https://youtrack.jetbrains.com/issue/QD-10354/GitHub-qodana-action-unable-to-find-a-non-default-config-file

If this works but is too noisy, do one of the following:
* Re-add the baseline/re-add 21575d1
* Turn PR Mode on. Note that this might miss copy/pastes from files outside the PR, so use with caution.
