Sergey Biryukov dd6d4e74c1 Code Modernization: Fix implicit nullable parameter type deprecation on PHP 8.4.
In PHP 8.4, declaring function or method parameters with a default value of `null` is deprecated if the type is not nullable.

PHP applications are recommended to ''explicitly'' declare the type as nullable. All type declarations that have a default value of `null`, but without declaring `null` in the type declaration, will emit a deprecation notice:
{{{
function test( array $value = null ) {}
}}}
`Deprecated: Implicitly marking parameter $value as nullable is deprecated, the explicit nullable type must be used instead`

**Recommended Changes**

Change the implicit nullable type declaration to a nullable type declaration, available since PHP 7.1:
{{{#!diff
- function test( string $test = null ) {}
+ function test( ?string $test = null ) {}
}}}

This commit updates the affected instances in core to use a nullable type declaration.
