This example repo currently defaults to "building the image every run".

This can cause issues with dependency drift, security patches or vulnerabilities introduced in later version, etc.

As a developer I want to be able to easily tell if my action is going to build an image every run, or use a published image from a container registry...

As a developer I also want to be able to read the documentation for both approaches and copy paste syntax from the examples for both approaches.
