chore(deps): update sentence-transformers requirement from >=5.7.0 to >=6.1.0

[dependabot]

Updates the requirements on sentence-transformers to permit the latest version.

Release notes

Sourced from sentence-transformers's releases.

v6.1.0 - Documentation and input handling improvements

This is a small release with refreshed inference benchmarks, clearer documentation, and a few improvements to multimodal input handling.

Install this version with

# Training + Inference
pip install sentence-transformers[train]==6.1.0
Inference only, use one of:
pip install sentence-transformers==6.1.0
pip install sentence-transformers[onnx-gpu]==6.1.0
pip install sentence-transformers[onnx]==6.1.0
pip install sentence-transformers[openvino]==6.1.0
Multimodal dependencies (optional):
pip install sentence-transformers[image]==6.1.0
pip install sentence-transformers[audio]==6.1.0
pip install sentence-transformers[video]==6.1.0
Or combine as needed:
pip install sentence-transformers[train,onnx,image]==6.1.0

Changes

• Refreshed the inference benchmarks and efficiency guide, clarified benchmark labels, and documented ONNX CPU thread tuning (#3977, #4007, #3987).
• Added a shared input formats guide and SPARSEUP to the pretrained sparse model tables (#4036, #4038).
• Improved multimodal input handling and chat-template argument routing (#4037, #4048).
• Corrected loss formulas and argument descriptions in docstrings, clarified custom-module import requirements, and fixed links, typos, and optional type annotations.

For existing multimodal dict inputs, message content now follows each input's key order, which can change embeddings or scores. Video-frame URLs without recognizable image extensions need an explicit frame wrapper to remain one video. See #4037 for details.
