PR Summary

• Change in Project Ownership
  It appears like good 'ol switcharoo happened here! The project ownership has changed hands from "savannabits" to the new owner "opaweb". Our composer.json file got a little makeover reflecting this change. So, you'll see the project name and homepage URL updated accordingly. Now when you are looking for the project, you'll find it nestled in the arms of the new owner "opaweb". How exciting! 🔄🥳

Remember, the right name of the package now is opaweb/filament-flatpickr and its new home is located at https://github.com/opaweb/filament-flatpickr 🏡💻
