Anki add-on: Real-Time Import (updated for Qt6)

This is a version of Real-Time Import addon updated with a tiny fix to make it work on Qt6-based Anki installations. When the original is updated, let me know and I'll remove this one! I've tested this one on Windows 11, Anki 24.06.3 Qt6. Original description: Real-Time Import allows the Rikaisama and RikaiRebuilt Firefox extension to instantly add a note to an open deck. See the Setting up the Anki Real-Time Import Feature section on the Rikaisama webpage. Your firewall software might ask you to unblock Anki after this add-on is installed. Just click Unblock to continue. I've tested this on Windows 7, Windows XP and Linux Mint. Have Fun! cb4960 & Gareth
