[Housekeeping] Update aws-go-sdk to support EKS Pod Identity

[mthemis-provenir]

Describe the issue

Currently the Go AWS SDK in use is quite old and therefore doesn't support EKS Pod Identity, which is a much simpler way to allow service accounts to associate with a role.

The minimum required versions are found here.

What if we do not do this?

Users will continue to only be able to use IRSA (IAM roles for service accounts) annotations to associate service accounts with IAM roles, which is more configuration intensive.
