Fix quality-check CI working directory path

[clubanderson]

Fixes quality-check CI ENOENT failures affecting PRs #2105, #2106, #2107, #2108

Problem

The kb-quality-enforcement.yml workflow was running the quality checker from the scripts/ directory while the script tried to read files using repo-root-relative paths like fixes/cncf-generated/..., causing ENOENT errors.

Solution

Changed the workflow to:

1. Run the script from the repo root: node scripts/test-kb-quality-ci.mjs
2. Access the changed files list from the repo root: changed_files.txt

This ensures file paths resolve correctly when the script reads them.
