Add iPhotron project link to data directory

[OliverZhaohaibin]

This pull request adds iPhotron to AppImageHub.

The corresponding file in data/ contains the GitHub repository URL for automated inspection.

Thank you.

I reproduced the AppImageHub runtime locally using:

firejail --quiet --noprofile --net=none --appimage ./iPhotron-v4.3.0-x86_64.AppImage

The application starts successfully, the main process stays alive, and the GUI window is visible to X11 after startup:

0x2600013 "iPhoto": ("main.bin" "main.bin") 1200x720+122+77

I also confirmed that the process remains running:

/tmp/.mount_iPhotrBBHFNm/opt/iPhotron/main.bin

So the AppImage itself appears to be functional. The CI failure seems more likely to be related to AppImageHub/GitHub Actions runtime differences (timing, display/session setup, or other clean-environment differences), rather than a fundamentally broken package.
