updated webhook service port

[AndrewChubatiuk]

made service port for webhook the same as pod port
can be related to
VictoriaMetrics/operator#1094

As I understand, the old values are correct, but the user didn't expose 443 on their nodes for webhook svc?
If so, maybe we should provide a way to customize service port, wdyt?

as we do not customize http service port, so guess there's no need to customize webhook one as well, just made the value of webhook port the same as on container in the same manner as we have for http
