feat(ci): Indicate whether an image was pushed

[misund]

Adds an output that indicates whether an image was pushed.

Dependant workflows can use this output to evaluate whether they should
conditionally execute deployment or other downstream actions based on
whether image building occurred.

Changes:

• Add oci-image-pushed output to mage.yaml
• Add oci-image-pushed output to goapp.yaml and reusable-goapp.yaml
• Set output based on presence of var/oci-images.json file

Awesome! <3

Can I get an extra quick assessment about dashes versus underscores in the output variable name? I see that the neighboring oci-images is dash-cased..

Yeah, maybe copying oci-images and use dashes instead of underscores everywhere is a good idea

Yeah this would be an good idea i guess. But this one lines would do the same if i am correct

if: github.ref == 'refs/heads/main' && needs.mage.outputs.oci-images != ''

Either way is fine with me, I think mine seems more intuitive, on the other hand the customer-order-management version already works with the status quo
