Describe the bug
WSL broker in admin terminal fails: Unexpected winrt exception while launching accounts control from UI thread: '(pii)'.

To Reproduce
WSL version:

> wsl --version
WSL version: 2.4.13.0
Kernel version: 5.15.167.4-1
WSLg version: 1.0.65
MSRDC version: 1.2.5716
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.26100.1-240331-1435.ge-release
Windows version: 10.0.26100.3775

Launch Windows Terminal as administrator, in WSL with enable_broker_on_wsl=True, acquire_token_interactive fails with:

Unexpected winrt exception while launching accounts control from UI thread: '(pii)'. Status: Response_Status.Status_Unexpected, Error code: -2147220999, Tag: 528315209

enable_pii_log (#590) is already enabled (Azure/azure-cli#28954), but the error message still shows (pii).

Expected behavior
acquire_token_interactive should work as expected.

What you see instead
acquire_token_interactive fails.

Elevated mode is currently not supported on WSL. We will update the code to return a more user friendly message for this scenario.
