Add Vitest as a test runner option in the CLI

[francislagares]

Hello Nx team!

I don't know if this may already be in your checklist but I would like to suggest adding Vitest
as an option for the test runner in the CLI as opposed to get Jest config out of the box.

Key points ?

Performance: Vitest offers a fast and efficient test environment, making the testing experience smoother, especially in larger projects.

Developer experience: Providing Vitest as a built-in option will improve the developer experience for those already using Vite in their projects or who prefer Vitest's API over alternatives like Jest.

Hopefully this makes sense to you.

Thank you for your great work and support !

Cheers.
