Architecture Diagram for 'Provisioning AWS Databricks E2 with an AWS Firewall' invalid #126

Hi!

I presume the goal of https://github.com/databricks/terraform-databricks-examples/blob/v0.2.17/examples/aws-workspace-with-firewall/README.md is to provision several Databricks clusters with AZ replication as distinct services across separate subnets.

The problem is the CIDR blocks of 10.4.0.0/22 and 10.4.1.0/22 collide because the first subnet captures all up to 10.4.3.254. So there's a collision in the defined subnets.

Not sure if this is my misinterpretation but makes the diagram seem inaccurate. Can someone clarify the expectations here?
