Describe the bug

No compatability with dbt cloud latest test syntax with argument keyword?

Version	Macro call	Yaml syntax
dbt ≤1.5	positional/named args	old YAML (combination_of_columns: [...])
dbt ≥1.6	arguments= keyword	new YAML (arguments: { ... })

Compilation Error in test dbt_utils_unique_combination_of_columns (models/identification.yml)
macro 'dbt_macro__test_unique_combination_of_columns' takes no keyword argument 'arguments'

dbt --version
Core:

• installed: 1.10.0-b3
• latest: 1.10.13 - Update available!

Steps to reproduce

tests:

• dbt_utils.unique_combination_of_columns:
  arguments:
  combination_of_columns:
  - col1
  - col2

Expected results

Actual results
