#426 forced me to update my debug configuration

[RafaelKr]

I'm working with IntelliJ IDEA and had the following debug configuration:

Note the :8000 in the Host field. After upgrading to Symfony CLI 5.8.9 my breakpoints were not hit anymore.
It took me some time to figure out that I had to remove the port in the Host field to make it work again.

Maybe it would be helpful to add a note to the release notes of 5.8.9. Maybe also a little hint in the release notes of the next release.

Edit: see #426 Remove port from $_SERVER['SERVER_NAME'] which is the correct behaviour, but caused me this issue.
