fix: story ComponentAnnotations['subcomponents'] to correctly use its own type for subcomponents rather than attempt to inherit from the component

[lburgess]

I believe that this fixes the underlying bug for the much discussed bug in Storybook:
storybookjs/storybook#23170

Hi ! When is this PR going to be merged ?

@starzje Is there another maintainer you can nudge to review this? Many thanks!

LGTM

The ComponentAnnotations.component type is:

  component?: (TRenderer & {
    T: Record<string, unknown> extends Required<TArgs> ? any : TArgs;
  })['component'];

So, as Required<TArgs> don't apply to subcomponents, changing subcomponents to

  subcomponents?: Record<string, (TRenderer & { T: any })['component']>;

...to match, looks like the right way to go.
