[Bug] Models require fivetran_utils 0.4.12

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the issue

Models won't compile on versions earlier than `fivetran/fivetran_utils` 0.4.12.

### Relevant error log or model output

```shell
Compilation Error in model stg_netsuite2__account_types_tmp (models/netsuite2/staging/tmp/stg_netsuite2__account_types_tmp.sql)
'dict object' has no attribute 'union_connections'. This can happen when calling a macro that does not exist. Check for typos and/or install package dependencies with "dbt deps".
```

### Expected behavior

Staging models compile successfully.

### Possible solution

Update packages.yml to the following.

```
packages:
- package: fivetran/fivetran_utils
version: [">=0.4.12", "<0.5.0"]

- package: dbt-labs/spark_utils
version: [">=0.3.0", "<0.4.0"]
```

Update packages.yml to require fivetran/fivetran_utils version >=0.4.12 and <0.5.0, keeping the existing spark_utils range. Run dbt deps, then compile the staging models, including stg_netsuite2__account_types_tmp; done means the models compile successfully without the union_connections error.
