Angular Component Test broken by changes in Angular 14.2.0 (tearDownTestingModule)

[aki-kesulahti]

Current behavior

Running Angular component tests fails:

2022-08-29 08:24:14: webpack compiled in 29272 ms (23942f0303cba40d)

  ExampleComponent
    1) "before each" hook for "mounts"

  0 passing (183ms)
  1 failing

  1) ExampleComponent
       "before each" hook for "mounts":
     TypeError: _angular_core_testing__WEBPACK_IMPORTED_MODULE_3__.TestBed.tearDownTestingModule is not a function

Because this error occurred during a `before each` hook we are skipping all of the remaining tests.

Angular (latest) version 14.2.0 version changed something in that part of their code:
https://github.com/angular/angular/blob/main/CHANGELOG.md#1420-2022-08-25
core - fix align TestBed interfaces and implementation (#46635)
angular/angular@7968402
angular/angular#46635
The change affected the public API surface, but in practice those types were already exposed via the TestBedStatic interface, so those APIs were already public.

I think Cypress Angular Component Tests needs to update how they use that mentioned API.
