VARCHAR data type inconsistent

The provider version you are using.

1.3.1

The version of Terraform you were using when the bug was encountered.

Describe the bug

When defining a snowflake_table with columns of type VARCHAR(16777216) it creates successfully but any subsequent terraform plans show it wants to modify the column to VARCHAR(16777216) because the type is VARCHAR

      ~ column {
            name     = "NAME"
          ~ type     = "VARCHAR" -> "VARCHAR(16777216)"
            # (1 unchanged attribute hidden)
        }

Updating the resource definition to VARCHAR seems to cause the opposite effect

      ~ column {
            name     = "NAME"
          ~ type     = "VARCHAR(16777216)" -> "VARCHAR"
            # (1 unchanged attribute hidden)
        }

This causes unnecessary diffs during terraform plans

Expected behavior

From Snowflake docs

If no length is specified, the default is the maximum allowed length (16,777,216).

https://docs.snowflake.com/en/sql-reference/data-types-text.html#varchar

Therefore VARCHAR and VARCHAR(16777216) should be synonymous and not show a diff
