Thach Hoang 0d1eae32be Fix debug examples after rollup (#5417)
Fix #5373.

- Remove references to removed file "../../build/deps.js"
- Update leaflet-include.js to point to "../dist/leaflet-src.js"
- Update watch to use the same destination file as rollup (dist/leaflet-src.js)
- Define getRandomLatLng where used
