fix: add cfn-lint ignore rules for new format validation checks

[roger-zhangg]

Summary

cfn-lint v1.49.0 (aws-cloudformation/cfn-lint#4442) expanded format keyword coverage, adding validation for several new AWS resource property formats. This causes 97 new lint errors on test fixture files that use placeholder/fake ARN values.

New rules added to .cfnlintrc.yaml ignore list

Rule	Description
E1041	Ref/GetAtt format mismatch — test fixtures use refs that resolve correctly at deploy time
E1156	Invalid IAM Role ARN format — test fixtures use placeholder values like some-arn
E1157	Invalid KMS Key ARN format — test fixtures use placeholder values like thisIsaKey
E1159	Invalid ACM Certificate ARN format — test fixtures use placeholder values like arn::cert::abc
W1031	Fn::Sub resolved value format mismatch — test fixtures use simplified ARN patterns

Context

These errors are not caused by any code change — they are triggered by the upstream cfn-lint release. The develop branch will also fail once CI re-runs with cfn-lint >= 1.49.0. This also unblocks #3913.

The test fixture files under tests/translator/output/ intentionally use simplified placeholder values for ARNs, which is consistent with how other checks (E3001, E3006, W3037) are already suppressed in .cfnlintrc.yaml.

Testing

Verified locally that cfn-lint 1.49.1 --format parseable produces 0 errors with this change.

Issue created on cfn-lint side for E1041 false positive

Reading only the description I thought that it didn't make sense to ignore E1041, but then I saw the other comment and the linked issue in their repo. Sounds good.
