Although this change will bring back the usual false positives (Patterns in switch are not supported at language level '20'), we need it because currently the action is failing using the EAP and it's preventing changes being deployed.

Once the linter jetbrains/qodana-jvm:2023.3 is released, we should be able to update it and set the languageLevel to JDK_21
