docs(js): align SDK docs with scrapegraph-js 2.1.0 type rename

[VinciGit00]

Summary

• Mirrors the breaking TypeScript rename in scrapegraph-js#17 (v2.1.0). All exported types and Zod schemas drop the Api prefix; ApiResult<T> is the only type that keeps it. Monitor input types become MonitorCreateRequest / MonitorUpdateRequest / MonitorActivityRequest.
• Updates sdks/javascript.mdx: adds a 2.1.0 breaking-change callout, renames FormatEntry[] → FormatConfig[] in the scrape and crawl parameter tables, and bumps the version pin.
• Bumps scrapegraph-js version pins >= 2.0.1 → >= 2.1.0 across services/{scrape,extract,search,crawl,monitor}.mdx and transition-from-v1-to-v2.mdx.
• Runtime JS remains unchanged, so all code snippets keep working as-is.

Validation

Endpoint extract tested against 5 live websites with scrapegraph-js@^2.1.0 — 5/5 returned status=success. Per-URL results will be posted as a PR comment. API key supplied by the user at PR creation time; not stored, logged, or echoed.

Test plan

• Mintlify renders the 2.1.0 callout and updated tables correctly
• FormatConfig is the type name users see when they Ctrl+click into the SDK
• All five services/*.mdx pages show the new version pin
• transition-from-v1-to-v2 guide mentions 2.1.0 as the upgrade target

Endpoint validation — extract (5/5 passed)

Run with scrapegraph-js@^2.1.0 (installed fresh from npm, confirmed the new prefix-free exports land at runtime). API key supplied by the user at PR time; not stored, logged, or echoed. Key names only — response payloads omitted.

Confirms the renamed v2.1.0 surface (ScrapeGraphAI() + sgai.extract({ url, prompt })) works end-to-end against the live v2 API.
