feat: multi-platform Docker images

[bripkens]

Why

More and more systems are running on the arm64 platform. For example, AWS EC2 instances with Graviton2 processors or ARM-based MacBooks. One of our customers is facing issues, because Newman does not run on ARM-based systems. More specifically, the postman/newman Docker image only supports the linux/amd64 platform.

What

This change enables the creation of linux/amd64 and linux/arm64 Docker images.

The change also removes the Docker image definition for Ubuntu 14.04 and Alpine 3.3. Both of these newman Docker images haven't been published in two years and can therefore be removed.

Hello, We also need ARM-support for postman/newman Docker image. Are there any updates on it?

[jaredtbates]

We're running into this too.

We are deploying Testkube internally, and we are running on this issue too. Latest postman/newman tag is 2 years old and only AMD64 :S What is blocking this MR to move forward?
