Docker automated CI test

Is your feature request related to a problem?

A failed Docker build is not currently caught in CI. Should a failed Docker attempt be made in production, the DevOps team gets alerted.

In addition, Docker-based PRs require manual review and execution, which takes more dev resources.

Describe the solution you'd like

We should have an automated test that:

1. builds a docker container
2. runs the docker container
3. opens local site provided by the docker container and validate some contents within. e.g. curl the local site.

Describe alternatives you've considered

Additional context

@tim-lai Currently, this project has a workflow named as nodejs.yml. For this issue, we can include a new workflow which performs automated test on PR and on updates to PR. We can check if docker build and run is successful or not, by following this section of README.
We can make curls to running docker container exposed to some port, cause opening a site as part of github action might not be needed. Please do correct me if I am wrong.
