[Bug]: Upgrading from v2 to v3 with published config breaks installation

[CasEbb]

What happened?

When you upgrade from 2.x to 3.x and you have config/icon-picker.php published, your Laravel/Filament installation breaks because the config can't be loaded anymore.

Class "Guava\FilamentIconPicker\Layout" not found  

How to reproduce the bug

• Install filament-icon-picker 2.x with Filament 3.x
• Upgrade Filament to 4.x
  • If you use Filament's official upgrade script, it suggests updating the icon picker to v3.

Package Version

3.0

PHP Version

8.4.14

Laravel Version

12.37.0

Which operating systems does with happen with?

macOS

Notes

This is something that could be noted in a changelog or upgrade guide, but the README contains a dead link to CHANGELOG.md

Same issue is there something we can do. Should we maybe uninstall package and reinstall is this bc we had an older version and then upgraded??

[krognome]

Oh I see! We should update our config bc the layout in old config no longer works?? I am doing this now I am 99% sure this will resolve the issue.
