docs(db): fix broken code examples in release posts

[KyleAMathews]

Summary

• Add the required queryClient and getKey options to Query Collection examples.
• Replace the nonexistent createQueryCollection calls with createCollection(queryCollectionOptions(...)).
• Fix the join callback arguments and Electric collection options in the 0.5 examples.
• Replace the undefined fetchNextPage() call with a live-query window that loads the next 10 rows.

Only code examples change. The posts' prose, headings, excerpts, and publication metadata are unchanged.

Checks

• Site content collection build and formatter check passed before the load-more example update.
• The load-more window was verified against a Query Collection request trace.
• git diff --check passed.

Summary by CodeRabbit

• Documentation
  • Updated TanStack DB guides with revised examples for query-backed collections, including normalized data, persistence, and on-demand loading.
  • Refreshed join and pagination examples to show current usage patterns.
  • Updated cache-policy and progressive-sync examples to reflect current collection configuration options.

📝 Walkthrough

Three TanStack DB articles update examples for collection setup, query-driven sync, pagination, Electric integration, and persistence. The examples now use updated collection options, query client configuration, key selectors, and join callback arguments.

Changes: TanStack DB articles

Layer / File(s)	Summary
Embedded collection setup src/blog/tanstack-db-0.1-the-embedded-client-database-for-tanstack-query.md	The examples use createCollection with queryCollectionOptions, a shared QueryClient, and key selectors for todo, user, and project collections.
Query-driven sync examples src/blog/tanstack-db-0.5-query-driven-sync.md	The examples update join callback arguments and collection options. The pagination example uses a live query collection and setWindow, and the Electric example uses shapeOptions.url and a todo key selector.
Persisted collection setup src/blog/tanstack-db-0.6-app-ready-with-persistence-and-includes.md	The persisted shopping-items collection example creates a QueryClient and passes it to queryCollectionOptions.
