Minor bug fix in the ping test module used by CCF.

loguru warning method is warning() and not warn()

[bvavala]

I think loguru uses logging underneath, so your fix should be related to this problem python/cpython#105376 (i.e., warn is deprecated).

Could this be generalized and replace all warn in the repo with warning?
