docs(learn): correct the example code for the consumption of response…

[tenkirin]

Description

Docs, fix #8321

Added await body.dump(); to explicitly destroy the response body before throwing an error.

  if (statusCode !== 200) {
+    // consuming the response body is mandatory: https://undici.nodejs.org/#/?id=garbage-collection
+    await body.dump();
    throw new Error(`Ollama request failed with status ${statusCode}`);
  }

Check List

• I have read the Contributing Guidelines and made commit messages that follow the guideline.
• I have run pnpm format to ensure the code follows the style guide.
• I have run pnpm test to check if all tests are passing.
• I have run pnpm build to check if the website builds without errors.
• I've covered new added functionality with unit tests if necessary.
