Horse Milestone Fix

Fixes this issue where families already created/created in CAS Sims wouldn't automatically get the "Got A Horse" Milestone + younger Sims will get it too (Infants through Elders), like it already happens to Cats&Dogs because Maxis forgot to put some more tuning.

Thanks to rory_nutt for letting me know about the issue.

✅CHANGELOG 27/02/2026:

• Updated tuning.🆕

🚨This mod requires Horse Ranch and Growing Togheter to work🚨
