We wanted to be able to use the IAM role provided by the EC2 instance metadata in order to access S3 via the Minio configuration. To do this, a new credentials chain is added that will check the following locations for credentials when an access key is not provided. In priority order, they are: 1. MINIO_ prefixed environment variables 2. AWS_ prefixed environment variables 3. a minio credentials file 4. an aws credentials file 5. EC2 instance metadata (cherry picked from commit c0880e7695346997c6a93f05cd01634cb3ad03ee) Conflicts: docs/content/administration/config-cheat-sheet.en-us.md does not exist in Forgejo
