docs: Consistently adopt recommended meta pattern

[bmulholland]

Updating docs with suggestion from #21221 (comment)

(If this is no longer the suggestion, then a direct export of meta would be cleaner instead. Like this: #21221 (comment))

Greptile Summary

This PR updates the TypeScript type definitions in code snippets for Storybook stories, improving type inference and aligning with recommended meta patterns.

• Changed Story type definition to use typeof meta instead of direct component type in /docs/_snippets/typed-csf-file.md
• Updated code snippets for Angular, common (TypeScript 4.9+), common (TypeScript), and Web Components renderers
• Maintained consistency across different renderer examples while applying the new type definition approach
• Aligned documentation with the suggestion from the related issue (Bug: Type support for Vue component slots in stories #21221) discussion
