[Tracking]: Officially deprecate addon storyshots

[yannbf]

Describe the bug

This is a tracking issue for officially deprecating @storybook/addon-storyshots.

Problem

Storyshots was replaced by the Test Runner over 1.5y ago but we are still supporting it via Github issues (12+ open, 300+ closed) & also via the feature flag storyStoreV7 disabled, which is a performance and maintenance problem for Storybook core.

Additionally, Storybook 8 will fully embrace storyStoreV7 and its on-demand architecture, meaning it will be the only option. Storyshots is incompatible with such architecture.

This project aims to provide a migration path for users who want to keep testing their stories successfully in Storybook 8, and hopefully get a better, more future proof experience.
