Fixes #3141

Type of change

How Has This Been Tested?

This should be ready for review. I however noticed that the docs build fails.

sphinx.errors.SphinxWarning: /home/jenielse/source/repo/opentelemetry-python/.tox/docs/lib/python3.9/site-packages/opentelemetry/_logs/_internal/__init__.py:docstring of opentelemetry._logs._internal.LoggerProvider.get_logger:28:py:class reference target not found: opentelemetry._logs._internal.Logger

This seems to be that Sphinx cannot find the reference for the Logger class in return types. Not sure why this is happening

Thanks for the PR!

Does the docs pass if you move the Logger class to end of the file?

I will give it a try. I did try on a different branch to upgrade to newest Sphinx and replace autodoc_typehints with the build in sphinx feature. That seems to resolve this issue but triggers others

Add an entry to the nitpick_ignore list for this if it doesn't go away.
