Describe the bug

When using cfn-lint to validate AWS CloudFormation templates, the tool fails to recognize db2-ae and db2-se as valid RDS engine types, leading to incorrect validation errors.

cfn-lint --template .\rdsdb2.yml                         
W2031 You must specify a valid Default value for pEngine (db2-se). Valid values must match pattern Has to be one of [aurora, aurora-mysql, aurora-postgresql, mariadb, mysql, oracle-ee, oracle-ee-cdb, oracle-se2, oracle-se2-cdb, oracle-se1, oracle-se, postgres, sqlserver-ee, sqlserver-se, sqlserver-ex, sqlserver-web]
.\rdsdb2.yml:6:5

Expected behavior

cfn-lint should recognize db2-ae and db2-se as valid RDS engine types without error.

I created the PR with changes. After making the changes on my local, no more errors:

cfn-lint --template .\rdsdb2.yml --format json
