missing semicolon in the parental-agents-documentation

In the BIND9 documentation https://bind9.readthedocs.io/en/latest/dnssec-guide.html?highlight=parental-agents#working-with-the-parent-zone-2 the mentioned code-snipped will not load:

...
parental-agents "net" {
    10.53.0.11, 10.53.0.12;
};
...

The parental IPs needs to be delimited with a semicolon, otherwise BIND will not start/load:

22-Feb-2022 11:05:08.964 config: error: /etc/named/named.conf:23: missing ';' before '10.53.0.12'

The correct documentation - which starts BIND successfully - should be:

parental-agents "net" {
    10.53.0.11; 10.53.0.12;
};
