Not compatible with Jest's resetMocks option

Hello,

First thank you for this great lib 😄

It seems that the way to use this library described in the documentation is not compatible with the `resetMocks` option of Jest.

Indeed, `next/dynamic` is only mocked for the first test and the real one is restored from the second test.

I don't know if it could be managed by the lib directly but it could be at least documented.

Start with the documented usage and a test using Jest's resetMocks option; inspect how next/dynamic is mocked between tests. Reproduce that the mock is restored after the first test, then either make the library compatible or document the required setup and verify that subsequent tests retain the intended mock.
