Storyshots: fix broken storyshots with angular

[mattlewis92]

Closes #23549

What I did

Storyshots + angular is broken in 7.x due to the ngModule metadata not being passed, which results in a crash here due to analyzedMetadata being undefined:

storybook/code/frameworks/angular/src/client/angular-beta/StorybookWrapperComponent.ts

Line 61 in 379e484

const { imports, declarations, providers } = analyzedMetadata;

Storyshots › Deprecated/Button V1 › A button without cu3ButtonV1 directive
    TypeError: Cannot destructure property 'imports' of 'analyzedMetadata' as it is undefined.

Fixed by correcting the type to no longer make analyzedMetadata optional and passing in the expected analyzedMetadata value.

How to test

I applied this patch locally to our application and verified that storyshots with angular now work.
