Andrew Ekstedt 98a0071a53 path,path/filepath: add Join examples with ".." components
People sometimes expect Join to trim .. components from its arguments
before joining, and are surprised that it doesn't. This is bad if they
were relying on that assumed behaviour to prevent directory traversal
attacks.

While a careful reading of the documentation for Join and Clean
might dispel this notion, it is not obvious at first glance.

Add a case to the examples to nudge people in the right direction.

Updates #40373
