Add Makefile and apko config for a local dev-container environment

[jamonation]

This is a bit of an experiment that I hope we can turn into a daily tool for Academy work with various supporting tools. To start it adds a Makefile with two targets, apko-build and dev-container.

1. apko-build: creates a local image for Academy development, using our cgr.dev/chainguard/apko image and the included apko.yaml file in this PR.
2. dev-container: runs the image with various volumes mounted into it, and ports forwarded with a copy of Hugo and nginx to start with.

Future versions can add things like autodocs, rumble code, chainlink and so on.

To test, run:

make apko-build
make dev-container

Once it builds and runs, use hugo serve --bind 0.0.0.0 and then visit http://localhost:1313 when it is ready.

To build and preview HTML files with the included nginx, run hugo -e local-dev, then visit http://localhost:8080.

Docker and make are the only prerequisites to run this I think.

I got an error when trying to run the make dev-container command. It seems there is some platform mismatch:

Ahh thanks for checking @erikaheidi - seems like the uname -m output is doing something strange with both amd64 and x86_64. I'll try to figure out how to set that properly.
