Allow file browser columns customization

Currently, Jupyter Notebook UI only displays "Last Modified" time
(e.g., "a year ago"). There is no option to view the file creation date.

Expected Behavior:
An option to display the file Created Date or at least a toggle to switch between Created Date and Modified Date.

Use Case:
When working with multiple notebooks or training materials,
it becomes difficult to identify newly created notebooks versus old ones,
especially when files are copied or restored.

Environment:
OS: Windows
Jupyter Notebook: 7.5.0
Browser: Chrome

The issue identifies the Jupyter Notebook file browser and requests a Created Date display or a Created/Modified toggle. Done means the option is available in the UI and distinguishes newly created files from older or restored files; no source file or test is named, so repository navigation is required first.
