Found an (other) way to stop using the (local) [AWS shared configuration](https://async-aws.com/authentication/credentials-file.html) in the Composer package [async-aws/core](https://github.com/async-aws/core) in the PHPUnit tests. 🥳

_This was an great Symfony hackday pair session with `@TmEuMail`-2020._

Also big shout out to `@xabbuh` and `@OskarStark` for the heads up in the right direction! 👍
