Rules are not applied when "empty" is specified for the preset

[takeshiemoto]

I discovered a bug where the rules written in the rules section are not applied when the following settings are written in pint.json:

{
    "preset": "empty",
    "rules": {
        "array_syntax": true
    }
}

I made a fix because ConfigurationFactory::preset([]) is not called unless "empty" is added to the available presets.

I tried writing the following code and compared the cases where "empty" is not present in $presets and where it is present:

$example = array();

When "empty" is not present:

❯ ./pint -v --preset=empty --test


  ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── Empty
    PASS   ........................................................................................................................................................................................................................................................... 0 files

When "empty" is present:

❯ ./pint -v --preset=empty --test

  +        $example = [];
           $path = Project::paths($input);

           $localConfiguration = resolve(ConfigurationJsonRepository::class);

It can be seen that the rules are correctly applied.

Yes, we need to add it in there.
