#122

This PR adds support for gbfs v3.1-rc to typescript language bindings

Changes:

• v3.1-RC introduced to typescript + tests
• auto generated files are no longer committed to the repo and will be generated when needed
  - files are generated on postinstall yarn install
• moved script logic out of typescript folder into root script folder
• updated cicd to include test check
• added testfixtures for v3.1-rc

LGTM. Thanks @Alessandro100!

I added a few suggestions.

It would be good that a dev from MobilityData reviews this PR 🙏

Suggestion to add area and country_code in the manifest.json test to cover MobilityData/gbfs#572.

Example was found in https://github.com/MobilityData/gbfs/blob/master/gbfs.md#manifestjson.

I think it would be more neutral to use random names and URLs for the test files instead of those from a real operator. Thoughts @emmambd?

Example was found in https://github.com/MobilityData/gbfs/blob/master/gbfs.md#manifestjson.

@richfab Makes sense to me!

@Alessandro100 Can you please update the test files with examples from https://github.com/MobilityData/gbfs/blob/master/gbfs.md#manifestjson?
