dns record for zone no empty string passed to api

[Syndlex]

Description

It is not possible to create a record for the zone.

https://github.com/ionos-cloud/terraform-provider-ionoscloud/blob/master/services/dns/record.go#L134C22-L134C22
This should also add a empty string as name to the request in case we want to edit the zone.

It would be better if we could use "@" as the origin as statet in the RFCs for DNS zonefiles.

code to reproduce

resource "ionoscloud_dns_record" "zone_tls_txt" {
  content = "a924g9cm3cqt07f269lusinhfo"
  name    = ""
  type    = "TXT"
  zone_id = ionoscloud_dns_zone.test.id
}

Expected behavior

create a record for the passed zone
