[6.x]: Custom cpTrigger not working

[white-lukas]

What happened?

Description

When using a custom cpTrigger, the login page is loading, but when submitting the login form it still posts to /admin/login as it's route is defined in the build file (resources/build/assets/LoginController-BCiywUg9.js)

Steps to reproduce

1. setup craft
2. set custom cpTrigger in general.php
3. try to login

Expected behavior

login form should post to {cpTrigger}/login instead of admin/login
