Update edge-tts to version 4.0.11

* Add pylint check for lint.sh
* Change overlapping default from 5second to 1second for SubMaker and util.py
* Default to WordBoundary for edge-playback (from SentenceBoundary)
* Drop SentenceBoundary support (never works properly and too many hacks)
  - No longer actually supported by Azure's official SDK for a few years
    already
* Stop attempting to correct broken offsets sent back to us by Azure
  - Fixes never work properly because AI voice sometimes takes odd pauses
    at the start and sometimes doesn't do so. It's never predictable and
    cannot be fixed on the library's end.
  - Solution is for Microsoft to fix the integer overflow bug they are facing
    in the {Word,Sentence}Boundary offsets. It doesn't affect us until we reach
    30min long TTS anyway.
* Have edge-tts --list-voices use the configured HTTP proxy
* More misc changes and fixes
