feat(ci): weekly Golf page redeploy every Sunday

[Copilot]

The Golf page pulls live content at build time, requiring weekly redeployment through the golf season without manual intervention.

Changes

• schedule trigger added to publish-astro.yml — fires every Sunday at 09:00 UTC (0 9 * * 0)
• The build job runs unconditionally on every trigger (push, workflow_dispatch, and schedule)

schedule:
  - cron: '0 9 * * 0'  # Every Sunday at 9:00 AM UTC

Trigger	Result
push to main	✅ deploys
workflow_dispatch	✅ deploys
schedule (every Sunday)	✅ deploys

<issue_description> In order to make sure the Golf content is maintained, we need to release once a week through the summer, April to October. Every Sunday morning the page should re-deploy updating the Golf Content and any future weekly updates that need to be handled.</issue_description>
