Move Python Training CUDA 12.2 pipeline to another pool. (#21745)

### Description
<!-- Describe your changes. -->



### Motivation and Context
[Python Training CUDA 12.2
pipeline](https://dev.azure.com/aiinfra/Lotus/_build?definitionId=1308&_a=summary)
has been always cancelled by remote provider since Aug 2nd.
But other workflows with the same pool haven't this issue.
 It looks like there're some weird things in Azure devops.
It works by using another pool. In fact, the SKU is smaller than the
old.
