• npm modules, source files and configurations which were added by feat(scripts): Automate the script generation for images #590 and feat(decrease image size): produce new slim images #597 have become obsolete and are no longer useable.

Changes

Remove unused and obsolete items.

Verification

Ensure that Cypress Docker image verification and test continues to work correctly.

Execute:

git clean -xfd
yarn
cd factory

Continue with

cd test-project
