Update AWS SDK to a version that supports EKS Pod Identity

[doubliez]

Is your feature request related to a problem? Please describe.
The current version of the AWS SDK used by Tolgee (2.20.8) does not support using credentials from an EKS Pod Identity association. The minimum version that supports that is 2.21.30, as mentioned in the AWS docs: https://docs.aws.amazon.com/eks/latest/userguide/pod-id-minimum-sdk.html

Describe the solution you'd like
Bump the AWS SDK to latest version 🙂

Describe alternatives you've considered
For now I still need to use IRSA (IAM roles for service accounts) in EKS to provide credentials to Tolgee, but EKS Pod Identity is the new recommended way of providing credentials in EKS.

Hey! Thanks for reporting. Pull request would be welcomed. We don't plan to use it this way, so it might be a bit harder for us to test this with real world case.
