[TRI-445] Update Docker image to follow Node.js Docker guidelines

[ericallam]

https://snyk.io/blog/10-best-practices-to-containerize-nodejs-web-applications-with-docker/

We need to go through this entire post and make sure we are following their suggestion in our Dockerfile, specifically these are most relevant:

• Use explicit and deterministic Docker base image tags
• Don’t run containers as root
• Safely terminate Node.js Docker web applications
• Graceful shutdown for your Node.js web applications
• Keeping unnecessary files out of the image
