`unit-test` builder with `vitest` runner should augment types with provider

[yjaaidi]

Command

test

Description

In Vitest 4, the import of @vitest/browse-* automatically augments the types of vitest/browser with provider's APIs specificities.

Angular CLI could either expose a vitest.config.ts using public Angular vite plugins, or in the meantime, the generator could add the provider's package to tsconfig.spec.json#compilerOptions.types or warn if it's missing or if there is a provider mismatch.
