fix(types): narrow voice in SpeechmaticsTTSSettings to disallow None

Browse Source 
After widening TTSSettings.voice to str | None | _NotGiven (so other
TTS services can opt into None as a valid "no voice" state), pyright
flagged Speechmatics' URL builder receiving str | None where it
required str.

Speechmatics has no "no voice" mode (the URL path includes the voice
name), so override the inherited field in SpeechmaticsTTSSettings to
str | _NotGiven. The call site stays as a plain assert_given(...)
without an extra None check.
