Invoke-AWSSSOLogin doesn't work when Windows is in FIPS mode

### Describe the bug

On a Windows laptop with FIPS mode enabled, running the Invoke-AWSSSOLogin commandlet fails with an error:

Invoke-AWSSSOLogin : This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

### Regression Issue

- [ ] Select this option if this issue appears to be a regression.

### Expected Behavior

Command should execute.

### Current Behavior

Invoke-AWSSSOLogin : This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

### Reproduction Steps

1. Enable FIPS mode in Windows by modifing the registry key HKLM\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy and seting the Enabled DWORD to 1 (may require reboot if this was not previously set).
2. Attempt to execute the Invoke-AWSSSOLogin commandlet with any valid parameters.

### Operating System and version

Start by reproducing the failure using Invoke-AWSSSOLogin on Windows 11 with FIPS mode enabled, then trace the cmdlet's authentication and cryptographic path. No source file or test is named in the issue; done means the command executes successfully with valid parameters under FIPS mode, with appropriate regression coverage if the project has an existing test location.
