AWS partner-central: Fix Boto3 sample: region_name parameter and SDK comment

Service: partner-central · 2026-09-27 · Documentation low

File: partner-central/latest/developer-guide/setup-authentication.md

Summary

Corrects a broken code sample parameter (`='us-east-1'` to `region_name='us-east-1'`) and adds a comment noting the sample requires the AWS SDK for Python (Boto3).

Security assessment

Purely a documentation/code-sample correctness fix for the X-Amzn-User-Agent client configuration; no authentication, authorization, or crypto behavior is described or changed.

Evidence

+    region_name='us-east-1',
