🚨 [open-formulieren/open-forms#2177] Patching react-leaflet-draw

The React-leaflet-draw package seems abandoned. As such, a fix for the typescript issue (alex3165/react-leaflet-draw#188) probably won't happen anytime soon

The .patch file, in `/patches`, contains the fix needed for the react-leaflet-draw index.d.ts file.

The problem with this solution, is that this only solves it for this project. If we introduce typescript to the SDK (or any other project using `react-leaflet-draw`), this problem will need to be solved again
