@qbittorrent/bug-handlers Just an FYI

Put this workaround to the end of src/base/tag.h and it should compile:

#include <QDebug>

inline QDebug operator<<(QDebug debug, const Tag &tag)
{
    debug << tag.toString();
    return debug;
}

However I consider that error to be a Qt bug. If it is not fixed in Qt 6.9 final release, I'll submit a PR.

Would you mind to submit bugreport to Qt?

I'm not fully certain about it, it wasn't a through investigation.
