Some questions:

• I had to tweak/fix some other files such as the test resources deployment script. That is not in the scope for this additional command. For the future, should fixes like that be in a separate PR or part of a PR like this?
• After running the tool description script, there were some changes made to other files like the eng\tools\ToolDescriptionEvaluator\prompts.json and eng\tools\ToolDescriptionEvaluator\results.txt. Should those changes be included? Many of the changes were in sections that are not Azure Managed Lustre related. Should I only include changes that are Azure Managed Lustre related?

Failed live tests are related to the test resources bicep file not creating HSM enabled AMLFS quite yet. This PR for AMLFS create should solve this issue.
