Description of Change

As explain in this issue, we cannot validate PR for recipes because pnpm validate is still a failure. Script compare the list of detected change where path are like "recipes/hangoutschat/package.json" and pkgJsonRelative contaning path to package.json with this format "recipes\hangoutschat\package.json". Of course, it never match.

Change : add path normalization on pkgJsonRelative
