  Clean up outdated references to Python 3.5
  *This is a good first issue for new contributors to take on, if you have any questions, please ask on the task or in our [Gitter room](https://gitter.im/freedomofpress/securedrop)!*
  
  ## Description
  
  SecureDrop now runs on focal, which uses Python 3.8. But there are still references to Python 3.5 that need to be cleaned up. Some should be dropped outright, others should be switched to 3.8.
  
  
  Some examples:
  ```
  $ rg python3\\.5
