fix: include managed_storage_configuration and avoid provider 6 at this time

[apollocatlin]

Description

Cluster configuration was missing managed_storage_configuration and providers need to be fixed to <6.0 to proceed at this time with tflint

Motivation and Context

managed_storage_configuration was missing
Incorrectly marked fix here: #215
Solves these two issues:

1. Encryption for Fargate Ephemoral Storage #258
2. Add support for managed_storage_configuration block #233

Breaking Changes

This prevents breaking changes in aws_region that need to be resolved for aws provider compatibility > 6.0.0

How Has This Been Tested?

• I have updated at least one of the examples/* to demonstrate and validate my change(s)
• I have tested and validated these changes using one or more of the provided examples/* projects
  There is no existing cluster_configuration example i have tested this in my own repository
• I have executed pre-commit run -a on my pull request
