Checks fail with error when installing ruby-filemagic

The Ruby & Rubocop checks fail with the following note:

An error occurred while installing ruby-filemagic (0.7.3), and Bundler cannot
continue.

In Gemfile:
  foodsoft_documents was resolved to 0.0.1, which depends on
    ruby-filemagic

Btw I just implemented a fix concerning some transport cost related issues and created a PR, then this error occurred.

I guess it might be a problem with the github CI … maybe the image ubuntu-latest the ci is based on does not contain the package libmagic-dev anymore
