Update msw and allow using existing msw server

[mlev]

Would be great to update to use msw v2, which has been out for approx 8 months. I was getting some weird issues and worked out it was because we're on v2 and this lib is only v1.

And generally for integration it would also be nice if you could optionally pass in an existing MSW server instance for this lib to reuse rather than creating it's own instance. i.e. as per recommendations from msw maintainer: mswjs/msw#821

Thanks!

Hi @mlev. This sounds like a good idea. Are you able to make a PR with the changes?

[mlev]

Have created PR. Instead of passing an msw server I exported the handler creation logic. Existing behaviour is unchanged but for my use case with my own server I wouldn't call jwksMock.start() any more. I already have my own msw server listening and I add the jwks handler to it with server.use(jwksMock.jwksHandler()).

Make sense?
