systems.csv: Provide structured authenticated schema

[emmambd]

Problem:

The MobilityData team is working to add GBFS feeds to the Mobility Database' API and website. This will enable easier automated discovery of GBFS data and provide more insights into GBFS data quality. You can see more about this work here.

Part of this work is pulling the data from systems.csv and adding it to the Mobility Database pipeline. Right now there's no easy way for us to auto-pull data from authenticated GBFS feeds because systems.csv does not make this easy to parse. There's just a generic "Authentication Info" field.

Solution

This PR includes 2 new columns so we can automatically determine what type of authentication is required and populate our private credentials automatically:

• Authentication Type
• Authentication Parameter name

It also includes updates to 6 systems in systems.csv that include authentication to match this schema change.
