ci(jscpd): improve output format #6373

## Problem
The output format of clones found in `jscpd` can be difficult to parse.
As an example, see
https://github.com/aws/aws-toolkit-vscode/actions/runs/12778633640/job/35621822359?pr=6370.
Additionally, it mentions file names and line numbers, but doesn't
provide a way to get to those files.

## Solution
- reduce friction by linking directly to the duplicates
