ci: remove library_versions workflow

[jar-b]

Description

This workflow was intended to check for the presence of net-new usage of the AWS SDK for Go V1. We have now migrated almost 80% of services off of V1 of the SDK and this check, while well intended, often misfires due to the way in which merges are applied on pull requests before producing a diff. For these reasons this check has likely outlived it's benefit and can be removed to reduce unnecessary pull request comment noise.
