chore: add karma-script-launcher plugin

This plugin is shipped as a default one with Karma. It's specified as a peer dependency.

I assume, there's an old version of NPM on the CI server, which does not support peerDependencies and therefore it didn't get installed.

This will make the dependency explicit.
