Fix FormRequest passedValidation data sync issue

[mosabbirrakib]

Problem:
When replace() or merge() methods are called in passedValidation(), the changes were not reflected in the validated() method because the validator instance held a copy of the original data.

Root Cause:
The validation flow in ValidatesWhenResolvedTrait::validateResolved() creates the validator instance before calling passedValidation(). When passedValidation() modifies the request data using replace() or merge(), the validator still has the old data, so validated() returns the original data instead of the modified data.

Solution:
After passedValidation() is called, sync the validator's data with the current request data using setData(). This ensures that any modifications made to the request data in passedValidation() are properly reflected in validated().

Changes:

• Modified ValidatesWhenResolvedTrait::validateResolved() to sync validator data after passedValidation()
• Added a test case to verify the fix works correctly
• The fix is backward compatible and only affects cases where data is modified in passedValidation()

Testing:

• Added testPassedValidationDataIsReflectedInValidatedMethod() test case
• Existing tests continue to pass
• The fix uses the existing validationData() method to get current data and setData() to update the validator

Fixes: #57659
