Container build: use npm ci over packages files and fix build cmd

[chalin]

In addition to fixing the issue named below, this PR has the container use the project's specified NPM dependencies, rather than using a separate list, keeping things DRY.

• Fixes make container-build command fails #48739
• Updates Dockerfile to:
  • Copy the project's package.json package-lock.json files
  • Run npm ci ... so that Hugo commands from the container use the same NPM packages we do in local development.
• Fixes container-build, and changes the command so that it writes to the local public folder, making it easier to debug generated files (without this change, the container build command fails because it can't write to ./public -- which means the only other alternative would be to write to another container-only folder such as /tmp/public, but I think that the solution proposed here is better).

I have verified in my local env that the make container-build command succeeded without errors. LGTM.
