Fix PHP 8.4 deprecation about Implicitly nullable parameter declarations with commit 6349a1b

[llaville]

One more PHP 8.4 deprecation fixed by commit aaa8950

[llaville]

Even if deprecations exists (it's for bartlett/sarif-php-sdk package that is not yet compatible with PHP 8.4, but will come soon)

Running unit tests with DB built on tests environment, with following command :

APP_ENV=tests vendor/bin/phpunit --configuration phpunit.xml.dist

Prints these output :

OK, but there were issues!

Requires these configs aaeec85 to run with PHP 8.4

For Info : my comment related is bartlett/sarif-php-sdk is only for version 1.x; Major version 2.0.x does not suffer this PHP 8.4 incompatibility.

No deprecations with bartlett/sarif-php-sdk 2.0.1 installed
