text: Title: Mac targeted Docker container
  Body: **Describe the feature you'd like**
  Docker container built for Mac users
  
  **Describe alternatives you've considered**
  The GPU container doesn't run at all:
  ```
  Error response from daemon: could not select device driver "" with capabilities: [[gpu]].
  ```
  
  And the CPU container runs very slowly.  Kokoro standalone can run on Apple M series chips much faster than what's available in the Docker images.
  
  **Additional context**
  Kokoro installed natively (`pip install kokoro`) runs faster than realtime; running in CPU mode in Docker it runs at about 1/5 real-time on my M1 Max.
