listen breaking change in 8.2 trixie fpm

[timogoosen]

This breaking change: #1635
That was only introduced here: in last commit 8.2/trixie/fpm/Dockerfile

is a breaking change for anyone depending on www.conf.
If you were doing something along the lines of:

listen = 127.0.0.1:9000

Then in www.conf change it to:

listen = 9000

Else Nginx or whatever webserver you are using with php-fpm won't be able to communicate.
