Install node and npm into development Docker images

[alchzh]

Currently, the Docker images include a pre-built copy of the frontend, and don't have the tooling to build the frontend themselves.

Something like

COPY --from=node:lts-bullseye-slim /usr/local/bin /usr/local/bin
COPY --from=node:lts-bullseye-slim /usr/local/lib/node_modules /usr/local/lib/node_modules

would be nice.

Which files would be affected?
build_image.py?

Does the proposed maintenance include non-doc string functional changes to the Python code?
No

Are you interested in implementing it yourself?
Not familiar with where this should go.
