docs: fix COPILOT_GITHUB_TOKEN setup command in gh-agent install guide

[github-actions]

Summary

• replaced the invalid gh aw secrets set command in docs/workflows/gh-agent-workflows.md
• updated the secret setup step to use the supported GitHub CLI command:
  • printf '%s' "(pat)" | gh secret set COPILOT_GITHUB_TOKEN --repo OWNER/REPO
• kept this aligned with scripts/quick-setup.sh, which already uses gh secret set

Validation

• docs-only change; no code/build/test impact

• verified the repository now has no remaining gh aw secrets set references and the docs command matches the setup script pattern

• Fixes [docs-new-contributor] New contributor docs review — invalid secret setup command in install guide #303

No phantom aw to cause dismay,
Just gh secret set to save the day! ✨
