Issues with aws-service-roles after upgrading to 2.3.0

#53 makes a change to completely ignore aws-service-roles. This raises an issue when you migrate to 2.3, it tries to create aws-service-roles as they are not "synced".

The fix I've implemented is to delete `aws-service-role/*` from our repo. I've documented this now in the releases page but we should do anything further?

### Note

You should remove all roles under `iam/roles/aws-service-role/` as these are no longer managed by iamy

這個 issue 與 iamy CLI 工具在升級後處理 AWS 服務角色的方式有關。檢查 issue #53 中引入忽略這些角色的程式碼變更。檢查 sync 邏輯，以了解 migration 如何嘗試建立這些角色。修正方式是從 repository 中移除 `iam/roles/aws-service-role/` 下的角色，如 releases 中所記錄。檢查專案結構以確認這些角色儲存在哪裡，並檢查 sync 流程以確保它們被正確忽略。
