[code-update-service]

🤖 This PR was raised by the code-update-service! 🤖.

Migrates GitHub Actions workflows from cloud-hosted runners (ubuntu-latest, ubuntu-24.04, ubuntu-22.04, ubuntu-20.04) to self-hosted runners (gha-production-medium).

Why this change?

This migration is to align all workflows for egress controls via Cilium network policies for our GitHub Actions cluster, improving security by controlling outbound network traffic from CI jobs.

• In this workflow the steps list items are indented at the same level as the steps: key (e.g., steps: then - name:). That makes the YAML invalid and the workflow may fail to load. Indent the step entries under steps: (and their nested fields) by two additional spaces so they are part of the steps array.
