[docs-scanner] Incorrect HTTP method name in backend.md

[docker-agent]

File: content/manuals/extensions/extensions-sdk/dev/api/backend.md

Issue

The page states:

See Service API Reference for other methods such as POST, UPDATE, and DELETE.

"UPDATE" is not a valid HTTP method. The actual HTTP methods available in the HttpService API are POST, PUT, PATCH, and DELETE.

Why this matters

Developers reading this will look for an "UPDATE" method that doesn't exist. The HttpService API reference clearly shows the available methods are get, post, put, patch, delete, head, and request - there is no "update" method. This is a factual error about the API.

Suggested fix

Change the text to accurately list the available methods:

See [Service API Reference](/reference/api/extensions-sdk/HttpService.md) for other methods such as POST, PUT, PATCH, and DELETE.

Or more concisely:

See [Service API Reference](/reference/api/extensions-sdk/HttpService.md) for other HTTP methods.
