refactor release promotion to allow for missing builds

[mattkjames7]

Description

An issue with the previous release was that we had to exclude some images from Docker Hub. The updated workflow should allow some images to be missing from the RC, but for the remaining images to be correctly handled.

This action run shows that this works. The two failures are unrelated to this problem (AWS permissions challenges!), but the remaining successful jobs manage to push and arm image without there also having to be an amd image; or in one case it "fails successfully" if there is nothing to upload - which is the point of this PR.
