fix(azure): update DatastoreType import

[冯基魁 (fengjikui)]

Summary

• Stop importing DatastoreType from the removed azure.ai.ml._restclient.v2022_10_01 namespace.
• Add a small promptflow-azure compat module that uses the available v2022_10_01_preview namespace and falls back to the old namespace for older SDK layouts.
• Update the two promptflow-azure call sites to share the compat import.

Fixes #4176.

Verification

• uv run --with azure-ai-ml==1.33.0 python - <<'PY' ... verified the compat module resolves AzureBlob, AzureDataLakeGen2, and AzureFile under azure-ai-ml==1.33.0.
• python3 -m py_compile src/promptflow-azure/promptflow/azure/_utils/_datastore_type.py src/promptflow-azure/promptflow/azure/operations/_artifact_utilities.py src/promptflow-azure/promptflow/azure/_storage/blob/client.py src/promptflow-azure/tests/sdk_cli_azure_test/unittests/test_blob_client.py
• uvx black --check src/promptflow-azure/promptflow/azure/_utils/_datastore_type.py src/promptflow-azure/promptflow/azure/operations/_artifact_utilities.py src/promptflow-azure/promptflow/azure/_storage/blob/client.py src/promptflow-azure/tests/sdk_cli_azure_test/unittests/test_blob_client.py
• git diff --check

I also tried the repository's poetry install --with ci,test from src/promptflow-azure, but dependency resolution did not complete locally after several minutes, so I kept local validation focused on the import compatibility path.

Still active from my side. I rechecked that the PR is mergeable and the visible checks are green; happy to adjust if the DatastoreType compatibility import should follow a different preferred path.

Still active from my side. The visible checks are still green, and I am happy to rebase or adjust the compatibility import path if maintainers prefer a different approach.

Still active. I rechecked this against current main@3928a727b406e66d64ff42621534bb58e0ca18ce: both promptflow-azure call sites still import the removed azure.ai.ml._restclient.v2022_10_01 namespace.

Fresh validation on exact PR head 371fe67b1aa8e584f0a92dac68a815d2ad8b6232:

• with azure-ai-ml==1.33.0, the old namespace raises ModuleNotFoundError, while the preview namespace and this compatibility shim load successfully with the expected datastore enum values;
• the focused test_datastore_type_compat pytest passed (1 passed);
• py_compile for all changed Python files and git diff --check origin/main...HEAD passed.

The PR remains mergeable, so no branch refresh appears necessary. Happy to adjust if maintainers prefer a different compatibility boundary.

Still active. The target branch is unchanged since the July 23 validation, the PR remains mergeable, and the visible checks are green. The two promptflow-azure call sites still need the compatibility import for current azure-ai-ml releases; happy to adjust if maintainers prefer a different boundary.
