Implicitly marking parameter as nullable is deprecated

Working on it.

I have made changes to remove implicitly parameters as nullable error on PHP8.4.
Please review.

Thank you, @divyansh.gupta

But now we need to run tests also with PHP 8.4 in pipeline. Let's start by adding OPT_IN_TEST_MAX_PHP: 1 under variables: in https://git.drupalcode.org/project/paragraphs/-/blob/8.x-1.x/.gitlab-ci.yml

@claudiu.cristea, Added it in the Gitlab-Ci file.
Please review.

Thank you. I see the PHP 8.4 phpunit test is failing

ok will work on those and make the test pass.

@claudiu.cristea
I have looked all the errors in the pipeline most of them are related to contrib or core files and there are no errors related to paragraph module files,
Please review.

There's an older, existing issue, please ensure that covers the same changes: 📌 Nullable types must be explicit Active
