Update DML 1.9 Nuget package to fix WindowsAI nuget pipeline build issue

[fdwr]

Description: Sheil K pointed out the WindowsAI nuget pipeline is failing to build due to a renamed file in the package.

Could not copy the file "D:\a\_work\1\s\csharp\test\Microsoft.AI.MachineLearning.Tests\packages\microsoft.ai.directml.preview\1.9.0-devd10042c94985065a565c042540e15eb75b554663\bin\x64-win\DirectML.d10042c94985065a565c042540e15eb75b554663.pdb" because it was not found.

Motivation and Context

Not sure what's happening in the "Linux CPU CI Pipeline", as this change doesn't even apply to that 🤷‍♂️:

ReadFileIntoBuffer failed for offset 0 and length 1 with error: ReadFileIntoBuffer - unexpected end of file. File: read_test_MO9tMp, offset: 0, length: 1

Retrying, again...
