text: Title: Add option to disable snapshot diffing
  Body: **Is your feature request related to a problem? Please describe.**
  
  <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] -->
  
  I have multiple massive (~10k lines) snapshots and if any of them fail it takes a considerable amount of time to produce the diff. I also don't need to know what the difference is in this case.
  
  An example snapshot can be found here: https://github.com/RobertCraigie/prisma-client-py/blob/main/tests/test_generation/exhaustive/__snapshots__/test_exhaustive/test_async%5Bactions.py%5D.raw
  
  **Describe the solution you'd like**
  
  <!-- A clear and concise description of what you want to happen. -->
  
  Add a new config / cli option to disable diff creation and instead just show an error that the snapshots differ.
  
  **Describe alternatives you've considered**
  
  <!-- A clear and concise description of any alternative solutions or features you've considered. -->
  
  None that I can think of.

  This was discovered from this CI run: https://github.com/RobertCraigie/prisma-client-py/runs/4859619412?check_suite_focus=true which I cancelled after 14 minutes (it usually takes at most 3 minutes to complete).
