Update Nginx

[dydx]

• Builds nginx version 1.24.0 from source rather than installing from outdated APT or trying to update python:2 to python:3
• Removes EOL version of remote docker in CircleCI

Locally, I can now see that nginx version: nginx/1.24.0 is installed and that it responds when spun up:

$> docker run --rm -it ttl.sh/replicated/replicated-installer:1h bash -c "nginx -v"

nginx version: nginx/1.24.0

And it appears that builds / tests succeed. Since the standard PR workflow does not actually build Dockerfile.prod, I temporarily placed that Job in the Workflow to see that it would build correctly in CircleCI
