Show command with nested json yields "Object of type ndarray is not JSON serializable"

Describe the bug

dbt-databricks throws Object of type ndarray is not JSON serializable when previewing nested json (dbt show)

Steps To Reproduce

• Open a databricks dbt project on your machine
• create a new model and paste the code snippet below into it
• run dbt show --select your_new_model

• This will throw Object of type ndarray is not JSON serializable

  
  with src_data as (
  
  select * from (
  values
     ('first json', '[{"obisCode":"1.8.0","interval":"00:05:00","rollOverLimit":999999.999,"values":[{"value":0,"registrationTime":"2023-01-31T21:16:35.5848643Z","measurementTime":"2023-01-31T21:15:00.0000000Z","quality":0,"isConfident":true}]}]')
  ) as (filename, series)

), cast_types as (

select

• except(series) , from_json(series,' array< struct< obisCode:string, interval:string, rollOverLimit:double, values:array< struct< value:float, registrationTime:timestamp, measurementTime:timestamp, quality:int, isConfident:boolean

  ') as series from src_data

), explode_series as (

select * , explode(series) from cast_types

) select * from explode_series

### Expected behavior
I expect this to result in previewed code as with other adapters:

filename	series	obiscode	interval	rolloverlimit	values	...
first json	[{"obisCode":"1.8...	1.8.0	00:05:00	999,999.999	[{"value": 0, "re...	...

### Screenshots and log output
