Version difference between s2i images and node version in Dockerfile

Currently, the Dockerfile uses node version 19 as a base image. However, that is not available for s2i.

We're using node version 18 for s2i in production, check here for available versions of node: https://github.com/sclorg/s2i-nodejs-container

Start by inspecting the Dockerfile's base image version and compare it with the available Node.js versions in the linked s2i-nodejs-container repository. Update the version so the Dockerfile and production s2i image use a supported release, then verify that the container build still succeeds.
