Is your feature request related to a problem? Please describe.
The goal is to be consistant with the others base entity classes like CreateAuditEntity, DeleteAuditEntity and UpdateAuditEntity

Describe the solution you'd like
Create the interface IAuditEntity<TAuditedBy, TAuditedOn> and implement it in AuditEntity<TId, TAuditedBy, TAuditedOn>

public interface IAuditEntity<TAuditedBy, TAuditedOn>
{
    TAuditedBy AuditedBy { get; set; }
    TAuditedOn AuditedOn { get; set; }
}
