Publish images to Docker Hub

[mrmeyers99]

I just found out that you can use pre-built images from docker hub in your github actions like this:

uses: docker://youyo/aws-cdk-github-actions:latest

I see that there is one image for this project published to Docker Hub, but it's old. It would be great if each new tag was published there so we can shave off a few seconds from each build we're running.

@youyo could this be implemented? It would reduce the CI/CD pipeline time significantly

FWIW I created a fork of the project and started publishing the images to GHCR.

The fork is https://github.com/mrmeyers99/aws-cdk-github-actions. Would love to get my changes merged back into this repo but @youyo hasn't been super active on this project lately. My fork also fixes #41.
