chore(docs): update versioned docs examples

[github-actions]

Generated by the Import versioned docs examples workflow.

The workflow imported the requested Handsontable documentation bucket(s)
with concrete npm dependency versions.

Note

Low Risk
Docs-only generated Sandpack JSON with a no-op-equivalent undefined check; no production or runtime service impact.

Overview
Re-imports the next versioned Sandpack bundle for the Getting Started Events and hooks JavaScript example (example1).

The embedded demo script now uses an explicit undefined check (str === undefined) instead of void 0 when skipping empty serialized hook arguments in log_events. Behavior is unchanged; this is a small style/clarity tweak inside the generated example payload.
