MachineLearning.GetTrainedModelsStats throws a deserialization exception part 2

[svalbuena]

Elastic.Clients.Elasticsearch version: 8.14.6

Elasticsearch version: 8.14.3

.NET runtime version: 8.0

Operating system version: Windows

Description of the problem including expected versus actual behavior:
I'm using the MachineLearning.GetTrainedModelsStatsAsync call to get the stats of a trained model, this request always results in a JSON deserialization error. In a previous issue I fixed one of the errors but there are a couple more left.
In elastic/elasticsearch-specification#2762 I describe the root cause and address it in elastic/elasticsearch-specification#2763.

This time, I've downloaded the .net client project, done the equivalent tweaks I'm doing in the spec project, and tested the request to verify there are no other errors left.

Hi @svalbuena, thanks again for creating the spec PR! The fix will be included tomorrow in the 8.15.0 release.
