Clarification needed for `trace_config` parameter documentation in TracerProvider

[chimchim89]

Hi,

I was looking at the TracerProvider docstring opentelemetry-sdk/src/opentelemetry/sdk/trace/init.py (lines 786 and 808) and noticed that the trace_config parameter still has TODO comments in the documentation.

Before opening a PR to complete the docstring, I wanted to check what the intended status of this parameter is. Is it still meant to be used by users, or is it kept for backward compatibility? I couldn’t find clear references to its current purpose.

Happy to submit a small documentation PR once I understand what should be documented here.

Thanks!

AFAIU, that is not used so I'm not sure there's much to document
