Minimal PHP Code Causing Issue

webmozart/assert latest have mixin code:

public static function nullOrTrue($value, $message = ''): ?true

which cause downgrade error

https://github.com/rectorphp/rector-src/actions/runs/26181495364/job/77025550737#step:14:77

Expected Behaviour

It should keep working.

Temporary solution is on PR:

• Temporary pin webmozart/assert to 2.3.0 to make downgrade working rector-src#7998

by temporary pin webmozart/assert to 2.3.0

I will create a real patch on downgrade rule for it next.

Reproduced at https://getrector.com/demo/6f56b825-773f-494b-8044-2c4c5f1753fc

which currently skipped, on php 7.4, it cause error:

Fatal error: Cannot use 'true' as class name as it is reserved in /in/cQbpV on line 6

which ?true should be removed and use docblock for it.

On check, it seems ?true only support on php 8.2+, so should be handled on php 8.2 downgrade.
