Fix quantified character class pattern anchors for backward compatibility

- Remove spurious $ anchors from simple patterns like ^[a-z0-9]{4,7}$
- Preserve $ anchors for complex patterns like certificate validation
- Fixed aws_signer_signing_job_invalid_profile_name.go spurious diff
- Refined pattern logic to only affect simple quantified character classes
- Maintains validation behavior while minimizing unnecessary diffs
