Fix ML.NET API docs

### Describe the issue or suggestion

[This include syntax](https://github.com/dotnet/machinelearning/blob/d9694c4b4810efd63fc7885b9e4efdd462aee3c5/src/Microsoft.ML.TensorFlow/TensorflowCatalog.cs#L23) doesn't [render](https://learn.microsoft.com/en-us/dotnet/api/microsoft.ml.tensorflowcatalog.loadtensorflowmodel?view=ml-dotnet-preview#microsoft-ml-tensorflowcatalog-loadtensorflowmodel(microsoft-ml-modeloperationscatalog-system-string)) properly on Learn (perhaps because the includes are within summary tags). **Note** that this does work in IntelliSense, so for that reason, perhaps we shouldn't work around the Learn limitation.

Include works when not within another tag: https://github.com/dotnet/machinelearning/blob/d9694c4b4810efd63fc7885b9e4efdd462aee3c5/src/Microsoft.ML.TensorFlow/TensorflowCatalog.cs#L11

And it works within remarks tags: https://github.com/dotnet/machinelearning/blob/d9694c4b4810efd63fc7885b9e4efdd462aee3c5/src/Microsoft.ML.TimeSeries/IidSpikeDetector.cs#L182
