Asana Ticket: 🚧 Splice together new Stoughton Branch shapes

So what's going on is, gtfs_creator has a new shape that we need to add to a test here. if the api test has the shape, gtfs_creator builds but the api itself won't pass the tests, because it uses the deployed version which doesn't have the new shape. if the api test has the shape, it will pass but then gtfs_creator won't pass its own tests. And we can't deploy gtfs_creator because it won't pass validation while using the master branch of the api.

anyway, we need to bypass the test check and merge this, so gtfs_creator can pass its build, we can deploy, and then the API will also pass the tests

[clem-hertling]

to be clear, this needs more than an approval (thanks @Whoops), bc it doesn't (and won't) pass tests (because it's pulling from gtfs_creator prod, which can't be updated until we merge this in because gtfs_creator CI can't pass without it

so it needs someone to bypass the merge protection (which I can't do, since I'm not an admin on the api repo)
