templates: Add dummy `RemoteAddr` to `httpInclude` request, proxy compatibility (#5845)

* Enhancement: Allow X-Forwarded-For Header in httpInclude Virtual Requests The goal of this enhancement is to modify the funcHTTPInclude function in the Caddy codebase to include the X-Forwarded-For header in the virtual request. This change will enable reverse proxies to set the X-Forwarded-For header, ensuring that the client's IP address is correctly provided to the target endpoint. This modification is essential for applications that depend on the X-Forwarded-For header for various functionalities, such as authentication, logging, or content customization. * Updated tplcontext.go - set `virtReq.RemoteAddr = "127.0.0.1"` i have made the suggested changes * Apply suggestions from code review * Update modules/caddyhttp/templates/tplcontext.go --------- Co-authored-by: Francis Lavoie <lavofr@gmail.com>
