feat(vite): add angular option to vitest generator (#29055)

## Current Behavior

`@nx/vite:vitest` generator does not provide Angular support in the
`uiFramework` options.

## Expected Behavior

`angular` option should generate the vitest configuration just like
`@nx/angular:application` and `@nx/angular/library` do.
