[AID] several issues

[tbischoff2]

The SMT contains several errors:

1. In EndpointMetadata of HTTP and MODBUS the base property has a wrong SemanticId.
   is: https://www.w3.org/2019/wot/td#base
   should be: https://www.w3.org/2019/wot/td#baseURI

2. The properties "property_name" in InteractionMetadata of all interfaces have a wrong SemanticId.
   is: https://admin-shell.io/idta/AssetInterfaceDescription/1/0/PropertyDefinition
   should be: https://admin-shell.io/idta/AssetInterfacesDescription/1/0/PropertyDefinition

3. All nested properties (all interfaces) have an observable property, which is an error according to the specification
