Migrate to Shortcut

[steaks]

#112

Migrates:

• Base url api.clubhouse.io -> api.app.shortcut.com
• References to Clubhouse in tests
• https://github.com/clubhouse -> https://github.com/useshortcut

Does not migrate:

• NPM package (still clubhouse-lib)
• Github repository name (still clubhouse-lib)
• References to clubhouse-lib in continuous integration
• Branding in README (e.g. logo)

^ I didn't migrate tasks on the does not migrate list because I didn't think I had permissions to do so. I think it'd make sense to have a Clubhouse employee complete the migration, but I'd be happy to help however I can. Thanks for building and maintaining this project Shortcut team!

Thanks for sending this, amazing! 🙌

You were faster than me on it. I'll be reviewing and merging this on Monday.

Thanks so much for sending this. 🙇‍♂️ 🎉

I'll take care of the remaining tasks. I was hoping I could generate a new TypeScript library based on our Swagger schema, so stay tuned for upcoming updates, your pull request definitely saved me time in the meantime.
