Currently the ChangeLogType is manually generated and does not include the serialization context logic when serializing / deserialzing.

There is a TODO in the code base because we have to manually deserialize from a BSON object. If we were to use an IDL generator we would not have to do such work manually and potentially lose / drop a tenantId since we are not carrying a SerializationContext over.

The NamespaceString in this case is constructed from BSON field values manually without a tenantId and without a serialization context which will be a problem once this code runs with multitenancy.
