chore(deps): update silero-vad requirement from >=5.1 to >=6.2.3

[dependabot]

Updates the requirements on silero-vad to permit the latest version.

Release notes

Sourced from silero-vad's releases.

v6.2.3 Make torchaudio optional

torchaudio is now an optional dependency instead of required. Only torch is required — the model itself never used torchaudio, only the read_audio / save_audio helpers did.

Users who need audio I/O must now install a backend explicitly:

• pip install silero-vad[audio] (torchaudio)
• pip install silero-vad[codec] (torchcodec)
• pip install silero-vad[all] (everything)

Key changes:

• read_audio / save_audio now work with either torchaudio or torchcodec; with neither installed they raise an error naming the extra to install
• Fixed: import silero_vad failed when onnxruntime was not installed — the sequence path is now imported lazily
• numpy is now declared in [onnx-cpu] / [onnx-gpu]

If you load audio yourself, no backend is needed at all:

from silero_vad import load_silero_vad, get_speech_timestamps
model = load_silero_vad()
audio = ...                                      # 1-D float32 torch.Tensor from any source
ts = get_speech_timestamps(audio, model, return_seconds=True)
