DDEV downgrade npm for Sulu CMS
Adding custom Javascript code to the Sulu Admin UI requires a rebuild of the administration interface frontend application. According to the Sulu docs, running the following command is enough:
bin/adminconsole sulu:admin:update-build
Sadly, this did not work in our ddev setup because ddev ships with a newer version of npm. Due to a breaking change for linked packages, Sulu is not compatible with npm > 6 at the moment.
