v3.23.0

Changed

• The ai-google (BETA) differ now defaults to using the new gemini-1.5-flash model (see documentation here <https://ai.google.dev/gemini-api/docs/models/gemini#gemini-1.5-flash-expandable>), as it still supports
  1M tokens, "excels at summarization" (per here <https://blog .google/technology/ai/google-gemini-update-flash-ai-assistant-io-2024/#gemini-model-updates:~:text=1 .5%20flash%20excels%20at%20summarization%2C>), allows for a higher number of requests per minute (in the
  free version, 15 vs. 2 of gemini-1.5-pro), is faster, and, if you're paying for it, cheaper. To continue to
  use gemini-1.5-pro, which may produce more "complex" results, specify it in the job's differ directive.

Fixed

• Fixed header of deepdiff and image (BETA) differs to be more consistent with the default unified differ.
• Fixed the way images are handled in the email reporter so that they now display correctly in clients such as Gmail.

Internals

• Command line argument --test-differs now processes the new mime_type attribute correctly (mime_type is
  an internal work in progress attribute to facilitate future automation of filtering, diffing, and reporting).
