Add support for jest-circus

[pavelrazuvalau]

Because of removing the jest-jasmine2 test runner, when I use the toBeObservable matcher I always get the following observable:

[{"frame": 0, "notification": {"error": undefined, "kind": "C", "value": undefined}}]

which makes it impossible to use jest-marbles with the latest version of jest.

If I understood correctly, it could be used with version <27.

Is it possible to add support for the newest version of jest with the jest-circus?

Thank you!

Is this still relevant? It seems to work just fine with Jest 29.

I believe this is indeed not relevant anymore. I have checked our repository using Jest v29 and ran npm ls jest-circus and npm ls jest-jasmine. There are no occurrences of jest-jasmine anymore. We do use the toBeObservable matcher extensively.
