Description:
------------
When configuring PHP8 alpha1 for apache by loading php8apache2_4.dll I configured the config line as:

--------------v
LoadModule php8_module "N:\Apache\php8\php8apache2_4.dll"

according to the longtime praxis of using 

LoadModule php7_module "N:/Apache/php7/php7apache2_4.dll"

This failed to load the module.

Instead I had to guess to use 

LoadModule php_module "N:\Apache\php8\php8apache2_4.dll"

instead which worked.

This change should be documented in the incompatible changes section of the release notes and by a correct example in the chapter for installing under Windows / under apache.

Environment:
- Windows server 2019 64bit Standard in a VM under HyperV
- Apache 2.43 64bit from apachelounge
- php 8 alpha1 64bit thread safe from php.net QA download
- php loaded as a module with php_module
