The documentation in the doc/CONTRIBUTING.md is misleading

[josephkabba]

Describe the bug
The docs/CONTRIBUTING.md file instructs contributors to manually edit scripts/contributors.js and add their filename to the contributorFiles array. However, scripts/contributors.js is auto-generated by scripts/generate-cards.sh, which is already run automatically in both CI workflows (deploy.yml and pr-preview.yml). Contributors only need to add their .html file to the contributors/ directory — the CI pipeline handles the rest.

To Reproduce

1. Open docs/CONTRIBUTING.md
2. Go to the "Add your card to contributors list" section (lines 81–91)
3. See that it instructs users to manually edit scripts/contributors.js
4. Check .github/workflows/deploy.yml and .github/workflows/pr-preview.yml — both already run bash scripts/generate-cards.sh automatically

Expected behavior
The "Add your card to contributors list" section should be removed or replaced, since the CI pipeline automatically generates contributors.js from the files in the contributors/ directory. No manual step is needed beyond creating the .html file.
