Update GBFS support to v2.3

[hannesj]

Summary

We might want to include new features from GBFS v2.3, such as the return constraints later on.

Issue

Currently we are unable to parse new form factors and propulsion types introduced in GBFS v2.3

I'm unsure if we need this distinction. We can discuss briefly in the meeting.

It's kinda nice to see that the Java compiler now helps to figure out where all the places are you need to change the code when adding an enum value.

I looked fast through this and @testower also approved, so this is good to go.
