What is the current behavior?

Mocking features cannot be used with Vitest. Attempting to do so would fail as Spectator mocks with Jasmine by default

ReferenceError: jasmine is not defined
❯ ../../../node_modules/projects/spectator/src/lib/mock.ts:76:58

Issue Number: #679

What is the new behavior?

A new secondary entrypoint @ngneat/spectator/vitest has been added, which exports Vitest-compatible mocking methods.

Does this PR introduce a breaking change?

[ ] Yes
[X] No

Other information

I have tried to add Vitest support the same way Jest support was initially introduced.

I still have to test this on fresh Jasmine, Jest and Vitest setups but so far it looks to be working fine.

This PR does not update the existing schematics.

LGTM

I still have to test this on fresh Jasmine, Jest and Vitest setups but so far it looks to be working fine.

I will wait for this to see that it still works fine. I recommend release it locally using Verdaccio and install the package on fresh projects

Thanks for the recommendation. It looks good after testing it with the 3 frameworks.
