Subject: [PATCH] Update prod to follow the release cycles (#547)

<!-- Provide a brief summary of your changes -->

## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
The following PR updates production to automatically receive new stable
releases when GitHub releases are cut while staging will continue
testing the latest main branch builds

Deails:
- Configures production deployment to **use latest stable** releases
instead of main branch
-`ghcr.io/modelcontextprotocol/registry:latest`(stable releases).
Released CLI matches version of the prod service API.
- Staging continues to **use main branch** for testing latest
development code - `ghcr.io/modelcontextprotocol/registry:main` (latest
development). Building the CLI from main would match the version of the
staging service API.
- Added environment-based Docker image tag selection logic

## How Has This Been Tested?

## Breaking Changes
