TypeScript getGeomanDrawLayers improvement

[hstevanoski]

I think the return type of the getGeomanDrawLayers method should be improved.
Currently, in leaflet-geoman.d.ts, we have the following:

/** Returns all Geoman layers on the map as array. Pass true to get a L.FeatureGroup. */
getGeomanLayers(featureGroup?: boolean): L.FeatureGroup | L.Layer[];
/** Returns all drawn Geoman layers on the map as array. Pass true to get a L.FeatureGroup. */
getGeomanDrawLayers(featureGroup?: boolean): L.FeatureGroup | L.Layer

The issue is that getGeomanDrawLayers doesn't return an array (missing [] after L.Layer), so you have to rely on the getGeomanLayers method to perform array-specific operations (not ideal in more complex scenarios).

Thank you for reporting, this is not the wanted behaviour, we will change it to L.Layer[].

@ryan-morris can you add this please in the next TypeScript PR?
