⛰ Airflow 3.0 - Initial Build and Testing

[jhpyke]

Brief summary of what this Epic is

This Epic captures the work required to set up and test the new Airflow environment in Analytical-Platform-Compute. This epic will cover all the internal work before we need to engage with users, but not the migration process from the old MWAA to the new one, as that will be it's own epic.
