  Split a string with a separator - while Jinja allows to call ".split" on a
  string, it doesn't natively bring a "split" filter implementation. We can't
  simply add further filters, since MkDocs doesn't allow it, so we're stuck
  with the function call. This however doesn't work with minijinja, which does
  not allow to call functions on template variables, but has a "split" filter.
  Thus, we just branch and extract the part that interests us here.
