CI is not showing the latest build via HTML previews

[mmcky]

Our ci.yml netlify upgrade in #599 is not showing the latest html on the links deploy-preview-{{ pr number }}. Perhaps this is reserved by netlify to do their own deploy-preview mechanism.

Here are the command options we are currently using:

              --context deploy-preview \
              --alias deploy-preview-${{ github.event.pull_request.number }} \

perhaps we should change our naming structure from deploy-preview to pr-${{ github.event.pull_request.number }} to ensure we don't overlap with netlify mechanisms. I looked at the netlify log and it says:
