msw + openapi-backend

[GuillaumeOj]

In the docs, there is a section dedicated to setup openapi-backend with msw (https://github.com/openapistack/docs/blob/7dccc49a61acec5dc39131b1045048c497789cd0/docs/examples/testing-react-with-jest-and-openapi-mocks.md). Unfortunately, the last versions of msw brings breaking changes (since v2): https://mswjs.io/docs/migrations/1.x-to-2.x/

I was not able to find a solution to fix the configuration with the v2. However, it could be nice either to update the docs are add a warning about the breaking change.

Thanks 🙏
