fix: Remove protected 'name' attribute from entity type models

Pydantic BaseModel reserves 'name' as a protected attribute. Removed
the 'name' attribute from dynamically created entity type models as
it's not needed - the entity type name is already stored as the class
name and dict key.

Fixed error: name cannot be used as an attribute for Requirement as
it is a protected attribute name.
