fix(ops/keycloak): ignore delete_default_mappers field r/8633

Without this, terraform wants to recreate the resource, just because we
do /not/ want to delete the default mappers:

```
  # keycloak_ldap_user_federation.tvl_ldap must be replaced
-/+ resource "keycloak_ldap_user_federation" "tvl_ldap" {
      + delete_default_mappers          = false # forces replacement
      ~ id                              = "4e68e9f0-7aba-4465-8357-f2af6a55fd0e" -> (known after apply)
        name                            = "tvl-ldap"
      ~ use_truststore_spi              = "ALWAYS" -> "ONLY_FOR_LDAPS"
        # (27 unchanged attributes hidden)
    }
```

Keycloak lists the a few mappers. which are likely the default ones,
but in any case, we don't want to recreate this resource.
