.env file always overiding environment variables when used in params

I've stumbled upon a bug reported here:
#6473

If configure my codeception.yml like this

params:
    - .env # load params from .env file
    - env # load params from environment vars

and a value comes both from .env file and ENV variable then the .env value is always used (no matter in which order you load the params).

In the original ticket the issue was fixed in #6477 however only SymfonyDotenv section was changed, could it be that the bug is still in if using PhpDotenv?

Codeception/src/Codeception/Lib/ParamsLoader.php

Lines 129 to 137 in cb4c200

    
           if ( 
        
               class_exists(PhpDotenv::class) && 
        
               class_exists(RepositoryBuilder::class) && 
        
               method_exists(RepositoryBuilder::class, 'createWithDefaultAdapters') 
        
           ) { 
        
               $repository = RepositoryBuilder::createWithDefaultAdapters()->make(); 
        
               $dotenv = PhpDotenv::create($repository, codecept_root_dir(), codecept_relative_path($file)); 
        
               return $dotenv->load(); 
        
           }

Using verions 5.2.2 at the moment:

> php vendor/bin/codecept --version
Codeception 5.2.2

could it be that the bug is still in if using PhpDotenv?

I'm not using vlucas/phpdotenv but according to https://github.com/vlucas/phpdotenv?tab=readme-ov-file#immutability-and-repository-customization existing values are overwritten by default.
Therefore, I guess the bug still exists for PhpDotenv.

@GameBurrow Do you want submit a PR to fix the behavior?
