Socket validation error : port should be integer

[air1one]

We have currently (on v3) validation errors on p2p like this :

Socket data validation error (peer 172.18.0.13) : Response validation failed from peer 172.18.0.13 : [{"ip":"172.18.0.10","port":"4000","ports":{},"version":"3.0.0-next.0","height":3,"latency":2},{"ip":"172.18.0.9","port":"4000","ports":{},"version":"3.0.0-next.0","height":3,"latency":5},{"ip":"172.18.0.12","port":"4000","ports":{"@arkecosystem/core-webhooks":-1,"@arkecosystem/core-api":4003},"version":"3.0.0-next.0","height":3,"latency":6}]

It seems it comes from "port" which needs to be integer (so 4000 instead of "4000") so we need to check where do we get it as string to instead keep it as integer.

The validation error can be seen easily on e2e tests on nodes 1 to 4.
