Issue #, if available:
Description of changes:
The s3 mb command now automatically detects account regional namespace bucket names (matching *---an) and sets the x-amz-bucket-namespace: account-regional header on the CreateBucket request. Previously, users had to fall back to s3api create-bucket --bucket-namespace for
this workflow.
v2: #10212
