GBFS Dataset catalogue updates

🚲 Shared Mobility folks, have we got some great news for you! Our catalog of GBFS datasets has grown a lot in the past year, but we’re always on the hunt for more sources of GBFS data. 

Currently, over 535 systems are represented. If your system isn’t yet in the catalog, please let us add it: https://github.com/NABSA/gbfs/blob/master/systems.csv. You can open a pull request or just get in touch with us at sharedmobility@mobilitydata.org, and we’ll do the rest.
