fix: remove callbacks arg from Tool and StructuredTool inferred schema

[aledelunap]

Fixes #5456

This PR removes the callbacks argument from a tool's schema when creating a Tool or StructuredTool with the from_function method and infer_schema is set to True. The callbacks argument is now removed in the create_schema_from_function and _get_filtered_args methods. As suggested by @vowelparrot, this fix provides a straightforward solution that minimally affects the existing implementation.

A test was added to verify that this change enables the expected use of Tool and StructuredTool when using a CallbackManager and inferring the tool's schema.
