docs(site): clarify splitReportFile output in consume-report-file docs

[yuyutaotao]

Motivation

• Clarify the difference between splitReportFile and reportFileToMarkdown in the consume-report-file documentation so readers understand that splitReportFile produces raw ReportActionDump-style JSON per execution plus exported screenshots while reportFileToMarkdown produces human-readable Markdown and its referenced screenshots.

Description

• Updated both English and Chinese apps/site/docs/*/consume-report-file.md to add an explicit explanation of the distinct outputs (*.execution.json + screenshots vs Markdown + screenshots) and recommend when to use each function.

Testing

• Ran pnpm run lint (failed in this environment due to biome scanning large files under ./.pnpm-store and hitting the configured files.maxSize), and ran npx biome check apps/site/docs/en/consume-report-file.md apps/site/docs/zh/consume-report-file.md --diagnostic-level=info --no-errors-on-unmatched which succeeded.
