chore: skip std spec tests (#4504)

## Description 
Currently, there are plenty of tests in a single file of any std test, and our current test scope (which duplicates resources by the number of tests) isn't handling it well, so we often get timeouts and exceptions.
Since the std tests' code is identical both on aws and the sim (and tested in the sim via hangar) I think we can skip it until the [testing issue](#3168) resolves.
