fix(dashboard): simplify and reproject France Regions map

SUMMARY

The previous version of the GeoJSON file was in EPSG 2154 projection and contained a high level of detail in the boundaries. This version has been reprojected to WGS84 (EPSG 4326) with the boundaries simplified, reducing the file size from ~12 MB to less than 900 KB.

I confirm that the new geojson file gets displayed correctly in the graph preview !
Thank you for the fix @dmeaux
It is very much appreciated.

It seems like we have conflicts that need to be resolved, but I'd love to get this merged. Also, do you know how to add/support this in the python notebook? I have a PR open to consolidate everything into that workflow, but right now the Italy Regions and France Regions maps are the exceptions I still want to sort out.
