TrickOps: Revert changes to trickops test yml file from Sept 2023

* trick_sims.yml was "accidentally changed" to remove unstable sims
  in Sept 2023, breaking the TrickOps unit tests. This reverts that change.
* Adjust new hashlib md5 comparison approach to work on systems where
  'usedforsecurity' isn't supported
