fix(core): use `realip_remote_addr` function to extract ip address

[Narayanbhat166]

Type of Change

• [x] Bugfix

Description

Previously we were relying on the X_FORWARDED_FOR header value for extracting the ip address. This value would be available if there were proxies that populate this value. But if this has been done from the localhost or if there were no reverse proxies behind the application, then this header value would not be present. This has been fixed in this PR.

We are using the realip_remote_addr function to extract the ip address from the request. This will look for the X_FORWARDED_FOR header, if not found, fallback to the socket ip address.
