When using --upgrade-from with an invalid tag it doesn't throw an error

[mjlescano]

When building an image using --upgrade-from some-package:invalid.tag with an inexistent tag it should throw an error and not continue the build.

For example, this should never work:

build omnibus-base-goerli.toml --upgrade-from synthetix-omnibus:99999 --provider-url https://base-goerli.gateway.tenderly.co/<key> --chain-id 84531 --dry-run
