[Feature] Automate Docker Release

[emmyoop]

Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

Describe the feature

The Docker release is currently done manually and we often drop getting it out the door: dbt-labs/dbt-core#7571. We already have a workflow to complete the process. let's add a workflow_call step, move it from dbt-core to this repo and then add calls in the release.yml in each repository to trigger releasing the docker image at the same time we release to github and pypi.

Describe alternatives you've considered

Continue to manually trigger the docker release

Who will this benefit?

Consumers of our docker images

Are you interested in contributing this feature?

No response

Anything else?

<= v1.7 dbt-postgres and dbt-core are released together. After that each package will be separate.

Keep the workflow_dispatch trigger to we can continue to trigger manually when needed.
