GitHub Pages publishing docs still show `actions/checkout@v4`, triggering Node 20 deprecation warnings

I have:

• searched the issue tracker for similar issues
• installed the latest version of Quarto CLI
• formatted my issue following the Bug Reports guide

Bug description

The GitHub Pages publishing guide currently pins actions/checkout@v4 in all three of its workflow examples (Publish Action, Jupyter+venv, Knitr+renv). Following these docs as written now surfaces GitHub's Node 20 deprecation warning, since actions/checkout@v4 runs on the Node 20 runtime that GitHub retired on Actions runners.

Note that quarto-cli's own CI moved off actions/checkout@v4 in #14199 (v4 → v6, along with actions/cache, upload-artifact, download-artifact, and setup-node), citing this same Node 20 deprecation.

Already fixed is the quarto-actions/publish README; this already carries a note that the action is compatible with actions/checkout@v6+, with @v5 as a fallback pin (referencing quarto-actions#133) — but that's a repo README, not a page on quarto.org, so it's easy to miss.

Ask:

Update the three actions/checkout@v4 references on the GitHub Pages publishing page to @v5 or @v6 so the copy-pasteable examples don't hand new users a deprecation warning.

Thanks Quarto Team!!

Steps to reproduce

Use the copy/pasted publish workflow from Quarto's GH pages publishing docs:

on:
  workflow_dispatch:
  push:
    branches: main

name: Quarto Publish

jobs:
  build-deploy:
    runs-on: ubuntu-latest
    permissions:
      contents: write
    steps:
      - name: Check out repository
        uses: actions/checkout@v4

      - name: Set up Quarto
        uses: quarto-dev/quarto-actions/setup@v2

      - name: Render and Publish
        uses: quarto-dev/quarto-actions/publish@v2
        with:
          target: gh-pages
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Use this to publish a quarto website and you get the Node20 warning.
