Describe the bug

When using cfn-lint version 1.4.0 to validate a CloudFormation template (template.yml) that includes tags for an AWS::Serverless::HttpApi resource, an error (E3012) is encountered. This error persists even when the tags are provided in what should be a valid format according to AWS CloudFormation specifications.

Error Message: The error message (E3012) suggests that cfn-lint is not accepting the provided tag format, even though it conforms to AWS CloudFormation's requirements.

E3012 {'Environment': 'Production', 'httpapi:createdBy': 'SAM'} is not of type 'array'

Similar to #3434. Working on a fix.
