aws-ec2 v5.46.1 - Removed dependency on workspace version policy for custom event patterns

Bug fixes

• The AWS > Turbot > Event Handlers > Events > Rules > Custom Event Patterns > @turbot/aws-ec2 policy previously depended on the Turbot > Workspace > Workspace Version policy, causing Event Handlers to run after a TE update. This dependency has been safely removed, improving the overall efficiency of the workspace.
