Looks like the "release-phar" action did not run (can't verify, I'm on phone)

It should be triggered by creating the release. However, my guess is that because we're using laminas/automatic-releases, downstream events are not triggered due to the GitHub access token being used. It might be possible to switch this out to use the personal access token for the organisation, which would cause downstream events to trigger actions in turn.

https://docs.github.com/en/actions/reference/authentication-in-a-workflow#using-the-github_token-in-a-workflow

When you use the repository's GITHUB_TOKEN to perform tasks on behalf of the GitHub Actions app, events triggered by the GITHUB_TOKEN will not create a new workflow run. This prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository's GITHUB_TOKEN, a new workflow will not run even when the repository contains a workflow configured to run when push events occur.
