If I understand the change correctly, the custom tag is always preferred. Does this mean that you only create releases with the custom tag? Otherwise, you use the normal logic? 🤔 If this is the case, I would adapt the documentation as it only affects the prod tag.

Correct; we have a monorepo and want to tag with prefix/version, and use the action to release code within the prefix folder with version version, so an initial step extracts both variables and the gitops workflow uses them.

I'll update the docs and rerequest review.
