> [!NOTE]
> **Low Risk**
> Single dependency pin in CI with no application or auth logic changes;
deploy behavior and inputs stay the same aside from the action runtime.
> 
> **Overview**
> Updates the **Deploy Platform API Docs** workflow to pin
`peaceiris/actions-gh-pages` from **v4.0.0** to **v4.1.0** (commit
`84c30a85…`). Deploy inputs (`personal_token`, `publish_dir`,
`destination_dir`, `keep_files`) are unchanged.
> 
> **v4.1.0** runs the action on **Node.js 24** (replacing Node 20 in
v4.0.0).
