 ----- 
- Automated content scope scripts dependency update

This PR updates the content scope scripts dependency to the latest
available version and copies the necessary files.

Tests will only run if something has changed in the
`node_modules/@duckduckgo/content-scope-scripts` folder.

If only the package version has changed, there is no need to run the
tests.

If tests have failed, see

information on what to do next.
