Implementing will be a bit more complex than just updating the GH Action like normal -- I have reusable workflows for releases here and for registry pruning here. These workflows are used across many of my repos, and some of my repos will not be able to support arm. As such, will have to be a flag that gets passed to the reusable workflow that toggles such functionality.

If anyone needs an arm image in the meantime, I've created one that is available here: https://github.com/oscarsiles/vault-unseal/pkgs/container/vault-unseal . Works well enough for me until official support is implemented.
