Guard Update Examples Cron on non-grafana forks

[Copilot]

The scheduled “Update Examples” workflow fails on forks because Vault secrets aren’t accessible outside grafana.

• Scope: Limit the update-examples-cron job to run only when github.repository_owner == 'grafana'.
• Outcome: Prevents secret fetch attempts (and resulting 401s) on forked repos; no functional code changes.

Example adjustment:

jobs:
  update-examples-cron:
    if: ${{ github.repository_owner == 'grafana' }}
    runs-on: ${{ github.repository_owner == 'grafana' && 'ubuntu-x64-small' || 'ubuntu-latest' }}
    steps:
      - uses: actions/checkout@v5
      # …
