fix: pass delete_objects to get_botocore_valid_kwargs in _delete_objects

[hsusul]

Description

Fixes an issue where awswrangler.s3.delete_objects passed function_name="list_objects_v2" instead of function_name="delete_objects" to get_botocore_valid_kwargs().

Root Cause

In awswrangler/s3/_delete.py, _delete_objects called:

extra_kwargs: dict[str, Any] = get_botocore_valid_kwargs(
    function_name="list_objects_v2", s3_additional_kwargs=s3_additional_kwargs
)

Because of this:

1. Valid S3 delete_objects parameters passed in s3_additional_kwargs (e.g., BypassGovernanceRetention, MFA, ChecksumAlgorithm) were filtered out and silently ignored because they are not valid parameters for list_objects_v2.
2. Conversely, parameters valid for list_objects_v2 but invalid for delete_objects (such as Delimiter or ContinuationToken) were incorrectly preserved and passed to s3_client.delete_objects().

Fix

Changed function_name="list_objects_v2" to function_name="delete_objects" in awswrangler/s3/_delete.py.

Testing

• Added regression test test_s3_delete_objects_additional_kwargs in tests/unit/test_moto.py verifying that delete_objects-specific parameters (BypassGovernanceRetention, RequestPayer) are retained and passed to s3_client.delete_objects(), while non-delete_objects parameters (Delimiter) are filtered out.
• Verified with pytest tests/unit/test_moto.py, ruff check, ruff format --check, and mypy.
• No AWS credentials or live AWS infrastructure required for testing.
