Sort allow-plugins alphabetically

[simPod]

I wonder where the new allow-plugins composer.json section could be sorted alphabetically?

I have disabled the sorting in ergebnis/json-normalizer#590 because I believe this could break the configuration for people doing something like this:

{
    "config": {
        "allow-plugins": {
            "my-organization/foo": false,
            "my-organization/*": true
        }
    }
}

When config.allow-plugins would be automatically sorted to

{
    "config": {
        "allow-plugins": {
            "my-organization/*": true,
            "my-organization/foo": false
        }
    }
}

then my-organization/foo would be allowed, while it was actually configured with the intention to be disallowed.

For reference, see https://github.com/composer/composer/blob/2.2.3/src/Composer/Plugin/PluginManager.php#L696-L700.

What do you think?

I see, did not come up with such use-case. I guess that makes sense then. Thanks!
