Fix GitHub Pages deployment workflow indentation error

[Copilot]

GitHub Pages deployment was failing due to incorrect YAML structure in the workflow file.

Changes

• Moved environment section from under steps to job level in .github/workflows/docc.yml

The environment key must be defined at the job level, not nested within steps:

deploy:
  runs-on: ubuntu-latest
  needs: build
  permissions:
    pages: write
    id-token: write
  environment:           # ← Correct: job-level
    name: github-pages
    url: ${{ steps.deployment.outputs.page_url }}
  steps:
    - name: Deploy to GitHub Pages
      id: deployment
      uses: actions/deploy-pages@v4

Original prompt

这个项目部署的GithubPages打不开了，曾经正常过，帮我修复
