When a new file/folder is added to a folder, it is assigned a default name instead of prompting the user to provide one.

### Description

I noticed that when we try to add a new file/folder by selecting a folder in CodeEdit it directly adds file/folder by the name untitled. Shouldn't it allow a blank cursor and let user add name of file and folder.

### To Reproduce

1. Open Any Folder in CodeEdit.
2. Try to add new file/folder from CodeEdit.
3. It adds file/folder by name untitled.

### Suggested Behavior

1. newly created file/folder should have blank place with cursor to allow user to add file/folder name.

### Version Information

CodeEdit: Version 0.0.3-alpha (37)
macOS: 14.3.1

### Additional Context

No response

Reproduce the behavior by opening a folder in CodeEdit and adding a file or folder from the project navigator. Trace the new-item entry point and verify that the created item enters name editing with an empty field and cursor, rather than using “untitled”; repeat the steps for both files and folders.
