Behaviour

Steps to reproduce this issue

Expected behaviour

The output is consistent across minor/patch releases.

Actual behaviour

The output now references context.payload.pull_request.head.sha if running within the context of a PR. This should have been considered a breaking change, as other workflows that later try to use {{ github.sha }} expecting that the image was previously tagged like so will no longer work.
