Support AWS `sso_session` setup

[matan129]

Hi, this is a simple change - I have a setup with AWS SSO, specifically sso_session (docs).

It got implemented in the AWS Go SDK fairly recently https://github.com/aws/aws-sdk-go/pull/4885 - v1.44.298

Since it's just a patch version upgrade, it was just a simple matter of bumping the version.

Thanks
