what: - runs module and api integration tests in matrix strategy - v28 of jest comes with sharding support, which we can utilize when we upgrade - splits the tests by number of matrix jobs and run them in parallel - This introduced some flakiness in some specs, but couldn't reproduce locally. Those have been skipped for now. - uses swc/jest for added performance - Locally, a chunk took 90 seconds with babel and 30 seconds with swc. - This translated to 2 mins saved per shard in CI, but haven't tested this enough.
