Feature Request: Detect if image does not exist

[rtvu]

Currently, if the provided image does not exist, then check_if_library will receive a http 404 response and the script exit with an error.

Would it be possible to handle the use case when an image does not exist. If an image does not exist, it may be desirable to build this image.

Maybe add a boolean for image-does-not-exist as an output?

Hi @rtvu

Do you plan to always run the build step after the action, even on error? Because if the image doesn't exist it will always throw an error, unless we add an input to ignore pull errors or something like that.

I would only want to build if the error is due to image does not exist.

My use case is i want to use the flow to both update an existing image as well as create the initial image.
