Fix GitHub Pages deploy workflow failure by upgrading deploy action

[Copilot]

User description

Description

The deploy GitHub Actions job failed while creating a Pages deployment due to an invalid OIDC token validation path in the current action/runtime combination. This change updates the Pages deploy step to the current major action version to restore compatibility.

• Root cause
  • actions/deploy-pages@v4 failed at deployment creation with OIDC key/token mismatch.
• Change
  • Upgraded deploy step in .github/workflows/deploy.yml from actions/deploy-pages@v4 to actions/deploy-pages@v5.
• Scope
  • Single-line workflow-only change; no application/runtime code touched.

- uses: actions/deploy-pages@v4
+ uses: actions/deploy-pages@v5
