[add-resource] New Plugin GIS

[Brice Boucard]

I would like to add my new plugin GIS to the Grav Repository.
Here are the project details: bricebou/grav-plugin-gis

You can see the public live on grav.reclic.dev.

Like I said in my previous request, I'm not a developer... I've tried to do my best ;)

Thanks !
