Summary

Remove all repository-specific Prow job configuration for repositories being archived in knative/community#1802:

• autoscaler-keda
• backstage-plugins
• discovery
• eventing-autoscaler-keda
• kn-plugin-sample
• kn-plugin-service-log
• kn-plugin-source-kamelet
• security-guard

Remove main-branch and release-branch job inputs and their generated outputs, including presubmits, continuous tests, nightly publishers, and release publishers. Regenerate TestGrid configuration to remove the associated dashboards, and remove stale autobump exclusions and the old test-infra fork's approve-plugin entry.

The remaining repositories marked ARCHIVE in the tracking issue already have no repository-specific jobs configured here. Historical documentation links and shared organization-wide Prow policies remain unchanged.

This updates the original release-only scope: main-branch CI is also removed, including Discovery and plugin-sample. Removing the job inputs prevents release-jobs-syncer from recreating their jobs.

This PR does not delete release artifacts, change Knative Operator integrations, or remove the separate knative/release or downstream GitHub Actions configuration; those are tracked separately in the community issue.

Validation

• ./hack/generate-configs.sh (run twice; output is idempotent)
• cd tools/configgen && go test ./...
• Verified no retiring-repository job files or explicit active repository references remain in Prow configuration.
• git diff HEAD --check

Rebased on main and checked for anything new since v1.24. Nothing else to remove — the PR already covers the v1.24 jobs and main branch CI for the retiring repos.

Config generation is clean, configgen tests pass, and diff checks are clean.

Leaving this on hold for now.
