[Bug]: Dataset with named parameters fails in Pest 3 if parameters count mismatch

What Happened

We use shared datasets to provide data for multiple tests. The dataset uses keys to make the data readable. Not all tests require all parameters from the datasets. So, the dataset contains more items in the array than the parameters needed by the tests.

In Pest 2, this works without any issues. In Pest 3, this setup fails.

It would be great to have the same behavior in Pest 3 as in Pest 2. I want to avoid adding unnecessary parameters to tests that are not used in the test.

In the sample repository, I provide an example.

How to Reproduce

• Clone the sample repository
• Run composer install
• Run ./vendor/bin/pest
• The tests fail with this error

   FAILED  Tests\Unit\ExampleTest > dataset with less parameters count with (1, 1, 1) #2                   Error
  Unknown named parameter $parameterC

• Change the pest version in the composer.json to ^2.0
• Reinstall the dependencies
• Run ./vendor/bin/pest
• The tests pass

Notes

No response

Clone the linked sample repository, run composer install and ./vendor/bin/pest, then compare the result with Pest 2 by changing composer.json to ^2.0. Trace the failing named-dataset parameter handling from the reproduction; done means tests with unused dataset parameters pass under Pest 3 without requiring unnecessary test parameters.
