chore(chart-deps): update policy-reporter to version 3.8.1

[svcAPLBot]

This PR updates the dependency policy-reporter to version 3.8.1.

[Copilot]

Pull request overview

Updates the vendored policy-reporter Helm chart to 3.8.1, aligning chart metadata and dependency pinning while incorporating upstream template/value changes (HTTPRoute backendRefs explicit typing and a new ServiceMonitor enable toggle).

Changes:

• Bump policy-reporter chart version/appVersion to 3.8.1 and update the chart-index dependency pin accordingly.
• Update related image tags (UI + plugins) to match the newer chart release.
• Add explicit group/kind to Gateway API HTTPRoute backendRefs, and gate ServiceMonitor rendering behind monitoring.serviceMonitor.enabled (defaulted on).

charts/policy-reporter/values.yaml:1873

• monitoring.serviceMonitor.enabled was added with default true, but it lacks the usual # -- (...) documentation comment used throughout this values file. Adding the comment keeps the chart values self-documenting and aligns with the README table generation.

  serviceMonitor:
    enabled: true

charts/policy-reporter/README.md:636

• The new monitoring.serviceMonitor.enabled value is documented in the parameters table but the description cell is empty, which makes the generated documentation unclear. Add a short description (and ideally mention it is gated by monitoring.enabled).

| monitoring.serviceMonitor.enabled | bool | `true` |  |

• monitoring.serviceMonitor.enabled was added without a # -- doc comment, which results in an empty description in the generated/maintained values documentation. Add a short comment describing what the flag does and that it is gated by monitoring.enabled.

  serviceMonitor:
    enabled: true

charts/policy-reporter/README.md:636

• The README values table row for monitoring.serviceMonitor.enabled has an empty description, which makes the rendered chart docs less useful. Fill in a short description consistent with values.yaml.

| monitoring.serviceMonitor.enabled | bool | `true` |  |

• monitoring.serviceMonitor.enabled was added, but it lacks a # -- doc comment in values.yaml. This causes the README table entry to have an empty description and makes the option harder to discover/understand.

  serviceMonitor:
    enabled: true
    # -- HonorLabels chooses the metrics labels on collisions with target labels
    honorLabels: false

charts/policy-reporter/README.md:636

• The new monitoring.serviceMonitor.enabled row in the values table has an empty description, which makes the generated documentation less useful. Add a short description consistent with surrounding rows.

| monitoring.serviceMonitor.enabled | bool | `true` |  |
