List tenants in az-ad collection uses different audience than the rest of the objects #128

Description

@lawndoc

Summary

The az-ad collection tries to list tenants:

// Enumerate Tenants
pipeline.Tee(ctx.Done(), listTenants(ctx, client), tenants)

But the ListAzureADTenants function uses the resourceManager audience for its request:

// ListAzureADTenants https://learn.microsoft.com/en-us/rest/api/subscription/tenants/list?view=rest-subscription-2020-01-01
func (s *azureClient) ListAzureADTenants(ctx context.Context, includeAllTenantCategories bool) <-chan AzureResult[azure.Tenant] {
var (
out = make(chan AzureResult[azure.Tenant])
path = "/tenants"
params = query.RMParams{ApiVersion: "2020-01-01", IncludeAllTenantCategories: includeAllTenantCategories}
)
go getAzureObjectList[azure.Tenant](s.resourceManager, ctx, path, params, out)

This leads to an error when using JWT auth because the az-ad collection needs the Graph API audience.

2025-05-13T10:52:37-05:00 ERR unable to continue processing tenants error="invalid audience"

The rest of the collection steps in az-ad work as expected because they all have the Graph API audience.

Steps to reproduce

$env:GRAPH_JWT = (Get-AzAccessToken -ResourceUrl "https://graph.microsoft.com").Token
./AzureHound.exe --jwt $env:GRAPH_JWT --list az-ad --tenant "contoso.onmicrosoft.com" -o "./entraid.json"
