METAL-1831: Add periodic sync for NGS with rebasebot

[elfosardo]

Summary

This PR adds a new periodic rebasebot sync job to OpenShift's CI infrastructure for automatically rebasing the OpenStack networking-generic-switch project.

Changes

The PR adds a scheduled rebasebot job to the OpenShift CI configuration that will:

• Sync upstream OpenStack project: Automatically tracks changes from openstack/networking-generic-switch on the master branch
• Rebase into OpenShift fork: Applies those changes to OpenShift's openshift-networking-generic-switch:main branch
• Use ironic-bot credentials: Leverages the existing metal3/ironic infrastructure team's bot credentials and GitHub app (ID 259896)
• Run on schedule: Executes periodically at 10:40 AM on Monday, Wednesday, and Friday
• Notify on completion: Sends results to the team-ocp-metal-platform Slack channel
• Use consistent resources: Allocates 4Gi memory limits and 100m CPU/200Mi memory requests, consistent with other OpenStack jobs

The job follows the established pattern used by other OpenStack projects already configured in the rebasebot infrastructure (sushy, ironic, ironic-python-agent, ironic-prometheus-exporter), extending automated upstream tracking to the networking-generic-switch project.
