composer-plugin-api should not be alphabetized as a dependency

[danepowell]

Composer internally treats composer-plugin-api as a special dependency (alongside things like php or ext-json) and always places it ahead of other packages. This conflicts with Composer Normalize, which wants to sort composer-plugin-api alphabetically with other dependencies.

Steps required to reproduce the problem

1. composer require composer-plugin-api
2. composer require acquia/drupal-environment-detector
3. composer require --dev ergebnis/composer-normalize
4. composer normalize --dry-run

Expected Result

• Composer Normalize does not complain, since composer.json was build natively by composer and is already sorted correctly:

"require": {
  "composer-plugin-api": "^2.0",
  "acquia/drupal-environment-detector": "^1.2"

Actual Result

• Composer Normalize wants to move acquia/drupal-environment-detector above composer-plugin-api, conflicting with Composer's own sort logic

Thank you for reporting, @danepowell!

Will be fixed with ergebnis/json-normalizer#463. I will let you know when I release both packages!
