fix(@schematics/angular): add missing imports for focus and skip APIs in refactor-jasmine-vitest

`xdescribe`, `fdescribe`, `xit` and `fit` Vitest equivalents use a slightly different API. This change handles the `--add-imports` aspect where the appropriate functions are imported for these specific APIs.

Fixes #33021
