Skip cache before image in TypeScript (#937)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Adjusts `skipCache` to return `this` in types and aligns
implementation for proper fluent chaining.
> 
> - **JS SDK – `template`**:
> - **Types**: Change `skipCache` return type from `TemplateBuilder` to
`this` in `types.ts` (`TemplateFromImage`, `TemplateBuilder`).
> - **Implementation**: Align `skipCache` in `index.ts` by removing
explicit return type annotation to match `this` chaining.
