add support for Tuanjie engine

[unitycoder]

now that its available to download for all..

• [ ] probably needs settings checkbox? so that it doesnt try to scan tuanjie, if not used
• [x] find engine exe
• [ ] find recent projects (if different from unity)
• [ ] uninstall.exe properties is different, product name: "Tuanjie 1.7.0" vs "Unity 6000.0.59f2" (File version has "2022.3.62.0")
• [ ] editor.exe is tuanjie.exe (details, product version is similar as unity: 2022.3.62t1b1_hash... Unity: 6000.0.59f2_hash....)
• [ ] other differences?
