composer v2

Hi @benjaminkott ,

I would like to use the configuration installer, but I get an error installing ex. bk2k/config-typo3-stylelint
```
Installing dependencies from lock file (including require-dev)

This most likely is due to a custom installer plugin not handling the returned Promise from the downloader
See https://github.com/composer/installers/commit/5006d0c28730ade233a8f42ec31ac68fb1c5c9bb for an example fix
```

This seems to be a composer v2 issue. Can u fix this? Or point me to the direction how to use it?

Start by reproducing the reported installation of bk2k/config-typo3-stylelint with Composer v2 and review the configuration installer’s custom installer plugin and downloader handling. Compare its behavior with the Composer installers promise-handling example linked in the error; done means the package extracts successfully without the reported missing temporary archive error.
