docs: update workbook default query row limit to 10,000

[keydunov]

What changed

Updates the documented default row limit for workbook semantic queries from 5,000 to 10,000 in docs/content/product/exploration/workbooks/querying-data.mdx.

Why

The default row limit for workbook queries is 10,000; the docs lagged at 5,000. This brings the documentation in line with the current product default.

Notes for reviewers

• Only the default value changed. The adjustable maximum (50,000) on the same line is unchanged.
• This is the workbook UI limit, distinct from the Core Data API default (CUBEJS_DB_QUERY_DEFAULT_LIMIT, documented separately as 10,000).

Change reviewed: docs/content/product/exploration/workbooks/querying-data.mdx — single-line update of the documented workbook default row limit from 5,000 → 10,000.

Findings:

• Code Quality: Minimal, accurate, scoped to the one stale value. The adjustable max (50,000) is correctly left intact.
• Security / Performance / Testing: N/A — docs-only change.
• Documentation accuracy: PR description correctly distinguishes this workbook UI limit from CUBEJS_DB_QUERY_DEFAULT_LIMIT (Core Data API), which is documented separately. No conflicting references found.

Nothing to fix — safe to merge.
