Agent backup config fails with The AWS Access Key Id you provided does not exist in our records.

[equals215]

Hi, I'm currently trying to setup my Manager's backup feature using a S3-like endpoint, not an AWS one.
When providing this config :

s3:
 access_key_id: **********
 secret_access_key: **********
 provider: Minio
 endpoint: **********

This is what I get when I test it with the following command :

scylla-manager-agent check-location -L s3:test1-backup --debug

Note that I'm using a MinIO provider and I get an AWS related-error.
