Missing FTP support

Hello,

Since Qt6.x series has been released, FTP support is missing.

According to multiple threads on Qt forums opened, this is currently an issue :

• https://forum.qt.io/topic/136161/qt6-qnetworkrequest-and-ftp
• https://forum.qt.io/topic/139038/qt6-ftp
• https://forum.qt.io/topic/142212/qt-6-4-2-and-ftp-upload-windows-11
• https://forum.qt.io/topic/125203/qt6-qnetworkaccessmanager-ftp-connection-and-manipulation

Do support is in the roadmap ? (because alternative is to use external library like libcurl but this will increase development effort to make it compatible with Qt toolkit)
