feat(publish): Fail hard when Docker image doesn't exist instead of building

[devin-ai-integration]

Remove Docker image build from publish operations

Description

This PR modifies the connector publish pipeline to fail hard when a Docker image does not exist, instead of automatically building and pushing the image. The desired behavior is to expect the image is already published and fail if not.

Changes

• Modified CheckConnectorImageDoesNotExist to return FAILURE status when an image doesn't exist
• Removed build and push steps from the publish pipeline
• Updated docstring to reflect the new simplified workflow
• Maintained handling for pre-releases and already published images

Motivation

This change allows for incremental migration away from using airbyte-ci for publishing. By removing the automatic image building and requiring pre-published images, we create a cleaner separation of concerns between building and publishing operations.

Testing

The changes have been tested by verifying:

• The pipeline fails when an image doesn't exist
• The pipeline continues with metadata upload when an image already exists
• Pre-release handling works correctly

Received message in Slack channel #ask-devin-ai:

@Devin - Currently `airbyte-ci` tries to build an image during a publish operation. We'd love to move away from using `airbyte-ci` but we need to do so incrementally. We've found a loophole whereby if we pre-publish the docker image, `airbyte-ci` will notice it already exists and skip publish. However, this is fragile. Can we simply remove the docker image build and publish steps entirely from `airbyte-ci` publish operations? The desired behavior is to expect the image is already published and fail hard if not.
