Actions workflow broken for ubuntu

[renefritze]

I've created a new project from this cookiecutter (@ 82f4a6c).
The build workflow for macOS and windows work, but ubuntu results in errors (because the linter is only run there).

Run yarn run lint:check
  yarn run lint:check

Looks like there are some dirs hardcoded that should be template evaluations instead?

Just removing the jupyter-widget-testwidgets bits works for me.
