toggle Field on label between singular and plural based on relation type (#8817)

#7683 

![labelPlural](https://github.com/user-attachments/assets/3e620d7e-dd51-4e4e-a9ba-289f2685ddf3)

![labelSingular](https://github.com/user-attachments/assets/84739ac5-29b4-48c8-8a71-3f8f2816641b)
Hello,
I’ve implemented the logic for dynamically toggling the Field on label
between singular and plural based on the relation type selected by the
user. Here's an overview of the changes:

Added a variable selectedRelationType to store the user’s selected
relation type.
Based on this variable, I determine whether to use labelPlural or
labelSingular from the selectedObjectMetadataItem.
Please review my changes and let me know if there's anything that needs
improvement .
