Workflow summary shows failure when the Terminus token is uncached

[morganestes]

When using the action, the exit 1 thrown by the cache step bubbles up to the workflow and shows an error even if everything else succeeds.

Is there a way to prevent that error from bubbling, or a different way of cache checking that doesn't return an error exit code?

I just came here to post this, I'll work on a PR.
