Update app dev tutorial to include Go and Java

This change uses (linked) tabs to display code snippets and
language-specific commands for the user's desired programming language.

In order to use the sphinx-tabs extension, the version of Python used to
build the docs had to be updated. Since the `n42org/tox` Docker image
used had a very old Python version baked in, and there were no more
recent versions available, the `make docs` target now uses the official
Python image. In addition to providing a much more current Python
environment, this image natively supports arm64 in addition to amd64,
allowing docs to be built on Apple Silicon Macs.
