az acr check-health command fails with 'NoneType' object has no attribute 'split'

[CodeJourneys]

Describe the bug

The az acr check-health command fails with an error. Now that the API version for MGMT_CONTAINERREGISTRY is set to None in the Azure CLI profile, the check causes an AttributeError ('NoneType' object has no attribute 'split') when running check-health against a registry. This bug blocks registry health checking in affected environments.

Errors

The command failed with an unexpected error. Here is the traceback:
'NoneType' object has no attribute 'split'
Traceback (most recent call last):
File "..._shared.py", line 335, in init
if 'preview' in api_version_str:
TypeError: argument of type 'NoneType' is not iterable
... (see PR #33117 for full traceback details)

Issue script & Debug output

az acr check-health -n example -y

Expected behavior

The check-health command should succeed whenever run against a supported ACR instance, regardless of profile API version changes.

Environment Summary

azure-cli 2.85.0 or later
Python and OS environment: Windows/Linux/MacOS (any)

See PR #33117 for proposed fix.

Additional context

Proposed fix: PR #33117

The regression occurred after MGMT_CONTAINERREGISTRY API version was set to None in the profile, but the check-health code continued to assume a string version. Removing the outdated API version check resolves the crash.
