docs(react-query): add missing errorUpdateCount to useQuery return signature

[KangaZero]

Summary

errorUpdateCount is fully documented in the Returns section of the useQuery reference pages but is missing from the destructuring block at the top of the page — the first thing a reader sees when scanning the API.

Affected files:

• docs/framework/react/reference/useQuery.md
• docs/framework/solid/reference/useQuery.md

The source of truth in packages/query-core/src/types.ts (line 655) places errorUpdateCount between failureReason and the fetchStatus block, which is what this fix reflects.

  failureReason,
+ errorUpdateCount,
  fetchStatus,

How did you test this change?

Documentation-only change — no runtime behavior affected, no tests needed. Verified by:

1. Cross-referencing packages/query-core/src/types.ts line 655, which defines errorUpdateCount: number between failureReason and the fetchStatus-related fields.
2. Confirming errorUpdateCount is already present and correctly documented in the Returns section of both files (lines 249 and 366 respectively) — it was only absent from the top-of-page destructuring example.

Summary by CodeRabbit
