Catch errors due to connection issues (e.g., pulling image from Az CR)

CDCgov/pyrenew-hew has experienced the same error twice:

Error: buildx failed with: ERROR: failed to solve: cfaprdbatchcr.azurecr.io/pyrenew-hew:dependencies-latest: failed to authorize: failed to fetch anonymous token: unexpected status from GET request to https://cfaprdbatchcr.azurecr.io/oauth2/token?scope=repository%3Apyrenew-hew%3Apull&service=cfaprdbatchcr.azurecr.io: 401 Unauthorized

A similar error has been reported using AzureCR + Kubernetes here, with users indicating it works on the second attempt (same as in pyrenew-hew). Although this seems to be an error with AzureCR, it may be a good feature of the twosteps-container-build action to try to catch this error and do k number of attempts waiting in between (probably an issue with the size of the container?).
