[Bugfix]Fix Artisan Serve command issue when using stderr logging

[cezarpopa]

Hi,

i hope all is well, as this is my first PR on the project, I believe that the patch added covers the case where the request is missing a port number and follows the given guidelines in the pull request template.

If i messed up something badly apologies for that and feel free to close the PR, i am not extremely familiar with the project.
I followed the steps mentioned here: #49927 to reproduce the issue.

Thank you,
Cezar

Thanks for your pull request to Laravel!

Unfortunately, I'm going to delay merging this code for now. To preserve our ability to adequately maintain the framework, we need to be very careful regarding the amount of code we include.

If possible, please consider releasing your code as a package so that the community can still take advantage of your contributions!

If you feel absolutely certain that this code corrects a bug in the framework, please "@" mention me in a follow-up comment with further explanation so that GitHub will send me a notification of your response.
