[CDF-24289 ] extending line width when dumping yaml to avoid unwanted…

… line breaks (#1497)

# Description

Module defaults that caused long lines got unwanted line breaks: 

```
data_developer_source_id: <OBJECT ID FOR TEST/PROD DATA DEVELOPER ENTRA GROUP> # ex. xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx
```
turned into 

```
data_developer_source_id: <OBJECT ID FOR TEST/PROD DATA DEVELOPER ENTRA  # ex. xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx
    GROUP>
```
This is now fixed
