Description of your changes

Fixes #1317 Depends on: https://github.com/upbound/terraform-provider-aws/pull/243

This PR bumps the Terraform provider version to v5.50.0 and the Go version to 1.22 as the underlying provider uses Go version.

We need to make sure that the ClusterAuth.eks resource is functional as we also update the aws-sdk-v2 version to match the version consumed in the Terraform provider (relevant issue: #1248).

Thanks to @mbbush for the PR to upgrade Terraform provider. The commit with ID aca95c9 was cherry-picked, we appreciate his efforts in increasing our automated testing coverage 🙌
