fix: unbreak main workflows

[czeslavo]

What this PR does / why we need it:

Fixes main workflows by:

• fixing a compilation problem that was caused by concurrent merges of chore: switch to kubernetes-configuration types and clientset #6619 and Fix(translator): detect conflicts on credentials in translating Kong configuration #6585
• checking out PR references in reusable workflows called from checks.yaml that uses pull_request_target

[czeslavo]

We'll have to forcefully merge it as otherwise we won't be able to fix main workflows.
