New Lakebase instances are created as Autoscaling projects by default

New Lakebase instances are now created as Lakebase Autoscaling projects by default. Lakebase Autoscaling is the latest version of Lakebase, with autoscaling compute, scale to zero, branching, and instant restore. This default behavior applies when you create new instances using the UI, Database instance API, Terraform, or SDKs.
