[bug] RHEL AI AMI error in non spot

[adrianriobo]

DEBU running 'mapt aws rhel-ai create'            
DEBU context initialized for mapteedb1313         
DEBU result len 0 checking rhel-ai-cuda-aws-3.4.0-ea.1-* in us-east-1 
AMI rhel-ai-cuda-aws-3.4.0-ea.1-* could not be found in region: us-east-1

This is the same root cause as #772 — the AMI name pattern rhel-ai-%s-aws-%s-* has a trailing - before the wildcard that prevents matching AMI names without a build suffix.

Fix: #773
