'az webapp config ssl list' returns an empty list

### Describe the bug

`az webapp config ssl list --resource-group ` returns `[]` as the response,
while `Get-AzWebAppCertificate -ResourceGroupName ` returns the actual certificates.

It has previously been reported, and supposedly fixed, here:

* #18216
* #19777

(Although my problem doesn't seem to be a caching issue as described in the first issue because running the `Get-AzWebAppCertificate` first, then `az` command doesn't make it work)

### Related command

`az webapp config ssl list --resource-group `

and

`Get-AzWebAppCertificate -ResourceGroupName `

### Errors

No errors, just no results.

### Issue script & Debug output

I've added `--debug` to the `az` command and `-Debug` to the `Get-AzWebAppCertificate` command and noticed that `Get-AzWebAppCertificate` makes this request 👇 to Management API:

```
https://management.azure.com/subscriptions//resourceGroups//resources?$filter=resourceType eq 'Microsoft.Web%2FCertificates'&api-version=2016-09-01
```

While the `az` command makes a different one:

```
https://management.azure.com/subscriptions//resourceGroups//providers/Microsoft.Web/certificates?api-version=2023-01-01
```

So, maybe the problem is not necessarily the CLI, but that 👆 specific Management API version/request?

### Expected behavior

I expect the certificates to be included in the `az` output.

### Environment Summary

I'm running both on Cloud Shell.
