[BUG] After AzureCli@2 uses azure-cli==2.70.0 instead of azure-cli==2.65.0, importing azure.ai.ml module has ImportError: cannot import name '_T' from 'marshmallow.fields'

### Describe the bug

When using AzureCli@2 task in Azure DevOps, if I run a python script, in which I import modules from azure.ai.ml, it will have the error below.

It was working before when AzureCLI@2 has the azure-cli version as 2.65.0. I ran the same pipeline without any changes last week and it worked. But this week, when the azure-cli version is 2.70.0, this bug occurs.

### Related command

- task: AzureCLI@2
inputs:
azureSubscription: ${{ parameters.WRKSP_SVC_CONN }}
scriptType: bash
scriptLocation: inlineScript
workingDirectory: $(Build.SourcesDirectory)
addSpnToEnvironment: true
inlineScript: |
python -m sample

Inside the sample.py file:
from azure.ai.ml import MLClient, Output, command, dsl

### Issue script & Debug output

Not applicable

### Expected behavior

The error should not happen, and the import should happen successfully.

### Environment Summary

azure-cli 2.70.0

core 2.70.0
telemetry 1.1.0

Dependencies:
msal 1.31.2b1
azure-mgmt-resource 23.1.1

Python location '/usr/local/bin/python3.11'
Config directory '/home/AzDevOps_azpcontainer/.azure'
Extensions directory '/home/AzDevOps_azpcontainer/.azure/cliextensions'

Python (Linux) 3.11.11 (main, Feb 25 2025, 05:21:12) [GCC 12.2.0]

### Additional context

For running this Azure Pipeline, I use custom image from Azure Container Registry, and in that image, I installed azure-ai-ml==1.25.0

I have no issue running imports from azure-ai-ml==1.25.0 elsewhere. This issue only happens when I run this python file in the AzureCli@2 task. And I have to use AzureCli@2 because it can addSpnToEnvironment.

I have found a hotfix solution: I have to manually add this to every single AzureCli@2 task if I run a python file with azure.ai.ml imports in it:
`python -m pip install marshmallow==3.23.2`
It resolves the error, but this is not ideal at all. Please address this.

Reproduce the AzureCli@2 scenario with sample.py importing azure.ai.ml on azure-cli 2.70.0, then inspect how its bundled dependencies select marshmallow alongside azure-ai-ml==1.25.0. Done means the import succeeds without manually installing marshmallow==3.23.2, with coverage for the affected dependency combination.
