Cache renv dependencies earlier in docs workflows

[Copilot]

Docs workflows were only persisting dependency cache in post-job behavior, so runs that failed/cancelled during render could miss cache saves. This updates the workflow cache mode so dependency cache is written immediately after restore/install, before long render stages.

• Workflow cache timing

  • Updated docs-rendering workflows to use explicit non-post-job cache behavior in setup-renv:
    • .github/workflows/preview.yml
    • .github/workflows/publish.yml

• Behavioral impact

  • Ensures dependency cache is available to subsequent runs even if render steps fail or are interrupted.
  • Aligns cache persistence timing with the referenced approach.

• Configuration change

  - uses: r-lib/actions/setup-renv@v2
    env:
      GITHUB_PAT: ${{ secrets.GITHUB_TOKEN }}
    with:
      bypass-cache: never
