BUG: Auto-capitalization of names when editing names of clusters

### Is there an existing issue for this?

- [x] I have searched the existing issues

### What happened?

How to reproduce
1. Go to face clusters
2. Trying naming a cluster 'bill'
3. The application will automatically set it to 'Bill'

This is most likely a bug rather than a feature

Problem
- User might not want first letter capital, he might want the custom name he/she is giving

I would like to work on this
