Issue with Deleting App Service SSL Certificate - Thumbprint Not Found

### Describe the bug

When attempting to delete an App Service SSL certificate, the operation fails with an error stating "Certificate for thumbprint not found." Despite confirming the correctness of the thumbprint with the az cli command az webapp config ssl show --resource-group {resource-group} --certificate-name {name}

If I use command az webapp config ssl list --resource-group, it appears that this command returns only four certificates. Consequently, attempting to delete a certificate not listed in these four results in an error.

### Related command

az webapp config ssl delete --resource-group --certificate-thumbprint .

### Errors

Certificate for thumbprint 'xxxx' not found
