Feature request: Named capture groups don't show their names in results.

**Is your feature request related to a problem? Please describe.**

**Describe the solution you'd like**
"Group n" change to the capture group name I provided in regex.

Start by locating the JavaScript code that renders regular-expression capture results and handles named capture groups. Verify how unnamed groups are currently labeled, then confirm that named groups display their provided names in the results while existing matching behavior remains unchanged.
