**Description:** Update to the pathspec for 'git grep' in lint check in the Makefile
**Issue:** The pathspec {docs/docs,templates,cookbook} is not handled correctly leading to the error during 'make lint' -
   "fatal: ambiguous argument '{docs/docs,templates,cookbook}': unknown revision or path not in the working tree."
