Add a Github Action for running Kurtosis packages

[mieubrisse]

Background & motivation

We've had various users request a Github action for running Kurtosis packages. The pain is that it's actually a pretty significant load on users to make them learn how to get Kurtosis installed on a CI box, then run Kurtosis on their package.

Desired behaviour

There is a Kurtosis Github action that runs a local Kurtosis package (equivalent of kurtosis run .) with a one-liner. This can be customized with args and flags based on the package

How important is this to you?

Painful; the lack of this feature makes using Kurtosis frictionful.

What area of the product does this pertain to?

CLI: the Command Line Interface
