InterfaceType for AWS::EC2::NetworkInterface isn't clear enough

[w0rmr1d3r]

Hi there 👋 !

The InterfaceType for the resource AWS::EC2::NetworkInterface isn't clear enough. The allowed values are efa and trunk, and the default interface but under Allowed values it includes branch?

The documentation:

`InterfaceType`  <a name="cfn-ec2-networkinterface-interfacetype"></a>
The type of network interface\. The default is `interface`\. The supported values are `efa` and `trunk`\.  
*Required*: No  
*Type*: String  
*Allowed values*: `branch | efa | trunk` 

from https://github.com/awsdocs/aws-cloudformation-user-guide/blob/main/doc_source/aws-resource-ec2-networkinterface.md

What haven't I understood?
