Confluence installation guide page for xdebug is outdated

https://confluence.jetbrains.com/display/PhpStorm/Xdebug+Installation+Guide

This page explains how to install xdebug but the information is not up to date. I get an error message 

Error: homebrew/php was deprecated. This tap is now empty as all its formulae were migrated.

And we can also see this

https://github.com/Homebrew/homebrew-php

https://brew.sh/2018/01/19/homebrew-1.5.0/

• By 31st March 2018 we will deprecate and archive the Homebrew/php tap. Unfortunately we have been unable to maintain an acceptable, consistent user or contributor experience and CI workload through non-core formula taps in the Homebrew organisation so we are continuing to migrate widely used formulae into Homebrew/core and encourage more niche formulae and options to be supported outside the Homebrew organisation.

Where to report this and how to get it fixed?
