Publish docker images for official op-contracts releases

Hey OP team!

There's already an existing [Artifact Registry image called contracts-bedrock](https://console.cloud.google.com/artifacts/docker/oplabs-tools-artifacts/us/images/contracts-bedrock) that includes the relevant contracts as well as a `forge` package pre-installed. This is very useful in ensuring consistency across artifacts (e.g. to ensure that a supported version of `forge` is used) as well as minimizing the number of manual steps required to deploy contracts.

Unfortunately, the image is not built for all supported versions of `op-contracts`. For example, there doesn't seem to be an image for `op-contracts/v1.3.0` even though this is still the recommended Contracts version for pre-fault-proof networks.

Would it be possible to get the images for the official releases published to the registry? Thanks!
