Upgrade vendored :leaflet-providers JS to 1.10.2 to update available OSM tile providers and fix deprecated MapBox endpoint.

Before MapBox could no longer be used as an OSM tile provider as they recently deprecated their tile API endpoint (https://blog.mapbox.com/deprecating-studio-classic-styles-d8892ac38cb4)

This update of leaflet-providers from 1.9.1 to 1.10.2 uses the new MapBox endpoint, it also adds new tile providers and removes some ones no longer supported. See https://github.com/leaflet-extras/leaflet-providers/blob/master/CHANGELOG.md#1102-2020-07-31
