Summary

Updates the S3 external data source setup guide with three fixes:

  • Cross-account bucket policy: Adds a new section between Steps 3 and 4 explaining the bucket policy required when the S3 bucket is in a different AWS account than the IAM role. Without this policy, cross-account setups fail with AccessDenied.
  • S3 bucket region field: Documents the optional "S3 bucket region" field in Step 4, which allows users to specify the bucket's AWS region instead of relying on auto-detection.
  • Step reference fix: Corrects Step 4's Role ARN reference from "Step 2" to "Step 3" (the Role ARN is copied at the end of Step 3, not Step 2).

All changes verified against the platform source code for accuracy.

Fixes: CXP-788
