This updates our `jest` configuration to no longer use `babel-jest` and instead uses `@swc/jest` which is much faster. This also updates to the latest version of `jest`, fixes our `tsconfig.json` used for tests (previously types in `node_modules` weren't resolved correctly), and ensures `next/dist` isn't un-necessarily transpiled in `jest`.
