Can't create Snowflake External Table of table_format: delta

[WesleyBatista]

Describe the bug

Getting:

Encountered an error while running operation: Database Error
  001425 (22023): SQL compilation error:
  invalid property combination 'REFRESH_ON_CREATE'='true' and 'TABLE_FORMAT'='DELTA'

I've notice the macro doesn't account for the REFRESH_ON_CREATE field - docs.

The fix looks simple. I will come up with an PR.
