[ws-proxy] Remove the port number from "X-Forwarded-Host" header as it's already defined in "X-Forwarded-Port"

[felladrin]

Description

Remove the port number from "X-Forwarded-Host" header as it's already defined in "X-Forwarded-Port".

This is a suggestion from @ChakshuGautam, and it seems correct to don't have a port there.

How to test

• Open a workspace on the Preview Environment of this PR.
• Run curl lama.sh | sh
• Run gp preview $(gp url 8080) --external to open a browser.
• Confirm you see, in the terminal logs of the request, the "X-Forwarded-Host" and "X-Forwarded-Port" headers. The first should have only the host and the second, only the port.

Release Notes

Requests on ws-proxy won't contain the port anymore on the "X-Forwarded-Host" header. It will contain only the host. If you need the port, you can get it from the "X-Forwarded-Port" header.
