Description

This change supports upgrading Astro deployments from Airflow 2 to 3. This involves updating the version comparison logic to take into account the new runtime versioning scheme for Airflow 3 images.

Note that for the initial period of Airflow 3 availability, to upgrade a deployment from Airflow 2 to 3 will require setting the --force-upgrade-to-af3 flag on the astro deploy command.

Resolves #1815

🧪 Functional Testing

• Unit tests added/updated
• Ran astro deploy for an AF3 project on an AF2 deployment, hit expected error on missing flag
• Ran astro deploy --force-upgrade-to-af3 for an AF3 project on an AF2 deployment, deploy proceeded
