minimal corrections to avoid implicit nullable deprecation warning

[dealfonso]

I found a lot of warnings related to "Implicitly marking parameter XXX as nullable is deprecated, the explicit nullable type must be used instead" when trying to use Phug in PHP8.4.

[Fri Mar  7 13:36:04 2025] PHP Deprecated:  Phug\Compiler::compileNode(): Implicitly marking parameter $parent as nullable is deprecated, the explicit nullable type must be used instead in /Users/user/Coding/.../vendor/phug/phug/src/Phug/Compiler/Compiler.php on line 502
...

The warnings have been corrected by marking explicitly as nullable those parameters that default to null.

The process was assisted by using Rector, with the following code:

return Rector\Config\RectorConfig::configure()
    ->withPaths([__DIR__ . '/src'])
    ->withPhpVersion(Rector\ValueObject\PhpVersion::PHP_84)
    ->withRules([ Rector\Php84\Rector\Param\ExplicitNullableParamTypeRector::class, ]);

Fix #115

Please create a new release to update packagist

This is a breaking change because it drops support for PHP < 7.1, it will go in the next major release. For now you can use composer require "phug/phug:2.x-dev as 1.999" to install it.
