Summary by cubic

Fix incorrect FormData examples by switching to axios.postForm and cleaning up the README snippet. Updates EN/ES/FR/ZH docs to match v1.x guidance.

Description

• Replaced axios.post with axios.postForm in maxDepth examples.
• Unindented the README code block for clarity and simplified the security note wording.
• Applied the same fix across EN/ES/FR/ZH multipart-form-data pages.
• Reason: axios.postForm is the recommended API for multipart form submissions in v1.x; previous examples were misleading.

Docs

• No new pages. Corrected code snippets and wording to reflect the recommended postForm usage.

Testing

• No tests added; docs-only changes.
