Description

This PR updates the release stable version workflow with a new step to update the latest tag to the newly created SemVer tag, and updates the Docker Compose setup guide to checkout the latest tag when cloning the repository.

Motivation and Context

This would help prevent failures with starting the app server when running off of the main branch, specifically when a new enum variant has been introduced in the main branch, but is not available in the latest stable release. Checking out the latest stable release when running the Docker Compose setup would ensure that a compatible configuration file would be used, and thus reduce server startup failures.

How did you test it?

I've tested out the new step added in the stable release workflow by running the command locally, first by creating the latest tag manually to point to an old release, then by running the command to point to the latest stable release.
