Test Failure: MLDsaTests.IsSupported_AgreesWithPlatform

[vcsjones]

I am seeing this test fail when run against .NET Framework when running against main.

Steps to reproduce

1. Check out main (I was testing against 9703a4c)

2. Run .\dotnet.cmd test .\src\libraries\Microsoft.Bcl.Cryptography\tests\ -f net481 --filter MLDsa

3. Note: You need to be on Windows Insider Canary 27871.

4. Observe the following failure:

   [xUnit.net 00:00:01.12]     System.Security.Cryptography.Tests.MLDsaTests.IsSupported_AgreesWithPlatform [FAIL]
     Failed System.Security.Cryptography.Tests.MLDsaTests.IsSupported_AgreesWithPlatform [9 ms]
     Error Message:
      Assert.Equal() Failure: Values differ
   Expected: True
   Actual:   False
     Stack Trace:
        at System.Security.Cryptography.Tests.MLDsaTests.IsSupported_AgreesWithPlatform() in E:\code\runtime\src\libraries\Common\tests\System\Security\Cryptography\AlgorithmImplementations\MLDsa\MLDsaTests.cs:line 35
