Implement GH Actions to publish new release to GH Pages

[oybed]

Currently the redhat.com branch is used to host GH Pages under https://rht-labs.github.io/infographic/. While using relative paths work for this use-case, there are other consumers of this branch (e.g.: redhat.com) that need the various image, css and js paths to be absolute.

This issue is to track the work needed with GH Actions to do the following:

1. When a new release is published (based on master branch) it will trigger the GH action
2. Update any images/ css/ js/ references to use the absolute URL, i.e.: https://rht-labs.github.io/infographic/images/, etc.
3. Push the changes to the redhat.com branch
