Use `which` instead of `tar` as reference tldr page in tests #192

The page for tar changes pretty frequently. which was last updated in 2018 and is a rather simple command overall. So it is less likely that the reference in the repository has to be updated as often as the one for tar.

Also see conversation in #186.
