👷 [open-formulieren/open-forms#2177] Update build scripts

Both changes are needed for the leaflet-draw and react-leaflet-draw dependencies.

leaflet-draw uses images for the different markers, which are included in the css. For this to work with the scss build, .png and .svg files use the dataurl loader https://esbuild.github.io/content-types/#data-url

Typescript errors in the react-leaflet-draw dependency caused a typescript validation/error, which shouldn't happen. Using `skipLibCheck` in the tsconfig.json type issues in the node_modules folder are ignored
