os_recordset fix for names with multiple DNS record types (#19588)

* Fix for os_recordset.py to filter based on record type. Fixes https://github.com/ansible/ansible/issues/19572

* remove redundant variable

* Needing to use recordset ID to update and delete records. Using the record name for update/delete causes issues when A and AAAA records exist for a name

* Adding exception handling for dictionary item
