Implicit null

[ProtocolLive]

The Rector are not detecting the implicit null deprecation

return RectorConfig::configure()
->withPhpSets(php84: true);

function foo(int$bar = null){}

Deprecated: foo(): Implicitly marking parameter $bar as nullable is deprecated, the explicit nullable type must be used instead in php shell code on line 1

If you don't have runtime php 8.4 or have but have composer.json not define "php": ^8.4, you can enforce it via : ->withPhpVersion(PhpVersion::PHP_84), see

https://getrector.com/demo/75fcfb81-0ff1-4194-a5e0-603813d3f2d5

for note: upgrading code php should be step by step, see #8823 (comment) for reasoning.
