Describe the Task

As of January 24, 2024, the following warning messages began appearing on the MET GitHub action workflow runs:

[Build Documentation](https://github.com/dtcenter/MET/actions/runs/7642630271/job/20822701483)
Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v3, actions/setup-python@v4, actions/upload-artifact@v3. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

Our call to actions/checkout@v3 triggers this warning message, as do other similar actions. Recommend upgrading action version numbers as needed to move past this warning. Make these change in both the develop and main_v11.1 branches.

Can use the following commands to update:

cd .github/workflows
for file in `ls *.yml`; do 
  cat $file | \
  sed 's%actions/checkout@v3%actions/checkout@v4%g' | \
  sed 's%actions/upload-artifact@v3%actions/upload-artifact@v4%g' | \
  sed 's%actions/download-artifact@v3%actions/download-artifact@v4%g' | \
  sed 's%actions/setup-python@v4%actions/setup-python@v5%g' | \
  sed 's%actions/github-script@v6%actions/github-script@v7%g' > tmp;
  mv tmp $file;
done
