integration test different S3 compatible storage providers

We are using R2 for the hive cloud and minio for local development. However, self-hosters might use AWS S3, Google Cloud Storage. We do not want to accidentally break support for these storage engines. We should have some kind of integration/end2end test that ensures things like https://github.com/kamilkisiela/graphql-hive/issues/3461 or https://github.com/kamilkisiela/graphql-hive/issues/2736 are not happening.
