CloudFormation: Creating a launch template through CF add the CFT tags

When creating a launch template through CloudFormation, moto adds the CloudFormation template tags to the launch template (as it does for all tagged EC2 resources. https://github.com/getmoto/moto/blob/af6a1fd435747ee4120065bb1eb5afc7a1425a14/moto/cloudformation/parsing.py#L754-L758

moto behaves differenlty than AWS here: the CloudFormation tags shouldn't be added to the launch template.
