Add tools to docker images

[wogan]

Using the command option for aliases is great for some codebases where aliases don't always follow a basic pattern.

However when using the tool from a github action, the command scripts are fairly limited in what they can perform.

I'd love to have access to python or other scripting languages with first class json support, but I can understand wanting to keep the images simple.

It would be great however if at least jq was installed so I don't have to use sed/grep for json parsing and printing.
