Feature Request: Per item validation

[ziming]

It will be awesome if we can apply per tag item validation to this nova tag field

For example in filament you can do something like this, the validation rule will be applied to each item in the tags field.

TagsInput::make('tags')->nestedRecursiveRules([
    'required', 
    'string', 
    'regex:/^[A-Z]+-[0-9]+$/',
]);
