Use InvalidArgumentError in ONNX embedding

[ArivunidhiA]

Problem

The ONNX embedding function throws ValueError for invalid provider inputs,
but Chroma's convention is to use InvalidArgumentError for client-side errors.
This creates inconsistent error handling across embedding functions.

Fixes #3026

Changes

• Replace ValueError with InvalidArgumentError in ONNX provider validation
• Add InvalidArgumentError import

Testing

python -m pytest chromadb/test/ef/test_onnx_mini_lm_l6_v2.py -v

Result: 15 passed in 1.97s

Impact

• Backward compatibility: None - only changes exception type for invalid inputs
• Breaking changes: None

Reviewer Checklist

Please leverage this checklist to ensure your code review is thorough before approving

Testing, Bugs, Errors, Logs, Documentation

• Can you think of any use case in which the code does not behave as intended? Have they been tested?
• Can you think of any inputs or external events that could break the code? Is user input validated and safe? Have they been tested?
• If appropriate, are there adequate property based tests?
• If appropriate, are there adequate unit tests?
• Should any logging, debugging, tracing information be added or removed?
• Are error messages user-friendly?
• Have all documentation changes needed been made?
• Have all non-obvious changes been commented?

System Compatibility

• Are there any potential impacts on other parts of the system or backward compatibility?
• Does this change intersect with any items on our roadmap, and if so, is there a plan for fitting them together?

Quality

• Is this code of a unexpectedly high quality (Readability, Modularity, Intuitiveness)

[propel-code-bot]

The update spans the entire ONNX MiniLM embedding implementation so that every user-facing validation path now raises InvalidArgumentError, keeping the client API’s error semantics consistent across dependency checks, input verification, and other safeguards.
