Tokenizer and punctuation fixes, better remote config handling

[ZachNagengast]

This PR includes the following fixes and improvements:

• CI now uses pinned os versions for more devices as well as a test plan to retry flakey tests
• Default device support config has been update to match latest from remote
• Remote config and model endpoints now accept remoteConfigName as well as endpoint parameters
• Tokenizer loading improvements:
  • The tokenizer loader will now search in more locations locally before attempting to download from huggingface, including the model path.
  • There was a bug in the previous release which downloaded the tokenizer to the model path only, this fix will search for that location for backwards compatibility, but respect the tokenizerFolder if provided in the WhisperKitConfig, and downloadBase by default for downloading if needed.
• Fixed a bug in prepended punctuation merging if there was no initial value in cases where the input alignment words didn't start with a special token.
