Remove-MgServicePrincipalTokenLifetimePolicyByRef is not using the correct underlying HTTP Graph endpoint

Describe the bug

I am using Microsoft.Graph version 2.39.0 on PowerShell 7.
The commandlet Remove-MgServicePrincipalTokenLifetimePolicyByRef is not sending out the correct MS Graph endpoint leading to error

The MS Graph URL the commandlet https://graph.microsoft.com/v1.0/servicePrincipals/xyz/tokenLifetimePolicies/$ref?@id=abc sends out is wrong.

The correct MS Graph URL is https://graph.microsoft.com/v1.0/servicePrincipals/xyz/tokenLifetimePolicies/abc/$ref per https://learn.microsoft.com/en-us/entra/identity-platform/configure-token-lifetimes?source=recommendations#create-a-policy-and-assign-it-to-a-service-principal (step 4)

Expected behavior

It should make this correct request:
DELETE https://graph.microsoft.com/v1.0/servicePrincipals/xyz/tokenLifetimePolicies/abc/$re

_No response_

### Other information

_No response_

Inizia dal punto di ingresso del cmdlet Remove-MgServicePrincipalTokenLifetimePolicyByRef e confronta il relativo URI DELETE generato con la documentazione di Microsoft Graph token lifetime policy collegata nell’issue. Verifica che l’ID del criterio sia inserito nel percorso prima di /$ref, quindi esegui i test pertinenti del cmdlet o di generazione delle richieste, se disponibili; il lavoro è completato quando il comando invia all’endpoint documentato.
