Use \dontrun instead of \donttest for non-essential examples

This is not so nice for the user experience because of the
wrappers arround examples:

 ## Not run
 ...
 ## End(Not run)

but it is necessary to some extent to pass automatic CRAN
checks under all circumstances, which actually do run
the donttest examples since R 4.0 with a time limit of apparently
20min in total.
