[Documentation]: Specify expected preview types in TypeScript docs

[alexeyr-ci]

Describe the problem

https://storybook.js.org/docs/configure/integration/typescript has

// Replace your-framework with the framework you are using (e.g., react-webpack5, vue3-vite)
import type { StorybookConfig } from '@storybook/your-framework';
 
const config: StorybookConfig = {

for .storybook/main.ts, but no equivalent for preview.ts(x).

https://storybook.js.org/docs/configure#configure-story-rendering should probably include it as well.

I finally found it in https://storybook.js.org/docs/writing-stories/parameters#global-parameters.
