[microsoft/main] Update common Docker engineering infrastructure with latest

[dotnet-docker-bot]

Updates the common Docker engineering infrastructure with latest changes from the dotnet/docker-tools repo.

[Copilot]

Pull request overview

This PR updates the shared Azure Pipelines “publish” infrastructure to support an additional mode for publishing merged image info: publishing it as an OCI artifact to the publish registry rather than committing it to the GitHub versions repo. This fits into the repo’s eng/docker-tools pipeline templates by adding a single new boolean parameter and threading it through the stage/job wrapper templates to the publish job implementation.

Changes:

• Introduces a new useOciArtifactForImageInfo parameter (default false) to control how merged image info is published.
• Threads useOciArtifactForImageInfo through the common publish stage and the .NET-specific wrapper templates.
• Updates the publish job to conditionally run publishImageInfoArtifact (OCI artifact path) vs the existing publishImageInfo (git commit path).
