default_test_connection doesn't accept config shown in docs

https://sqlmesh.readthedocs.io/en/stable/guides/connections/#default-test-connection

default_test_connection:
 type: duckdb
 database: test.db

My config.yaml:

default_test_connection:
 type: duckdb
 database: test.db

% sqlmesh plan
Error: Invalid project config:
  Invalid field 'default_test_connection.type_':
    Field required
  Invalid field 'default_test_connection.concurrent_tasks':
    Field required
  Invalid field 'default_test_connection.register_comments':
    Field required
  Invalid field 'default_test_connection.pre_ping':
    Field required
  Invalid field 'default_test_connection.type':

  Invalid field 'default_test_connection.database':

Verify your config.yaml and environment variables.

Do the docs need updating? It's not shown that concurrent_tasks, register_comments, or pre_ping are required, and database parameter is shown but apparently not permitted. It's also not clear how to specify the type.

I'm seeing this behaviour on SQLMesh version 0.221.1

I would like to add the individual gateway test overrides work fine, e.g.

gateways:
  my_gateway:
    connection:
      type: azuresql
      host: database.windows.net
    test_connection:
      type: azuresql
      host: database.windows.net

etc.
