[phillipuniverse]

Describe your environment
With the just-release opentelemetry-instrumentation-flask 0.44b0 I get this from the flask instrumentation:

DeprecationWarning: The '__version__' attribute is deprecated and will be removed in Flask 3.1. Use feature detection or 'importlib.metadata.version("flask")' instead.

Problematic code is at https://github.com/open-telemetry/opentelemetry-python-contrib/blame/8daa8ad48108775d8e799a3abc3ed06f84b4c00e/instrumentation/opentelemetry-instrumentation-flask/src/opentelemetry/instrumentation/flask/__init__.py#L254-L263 and caused by #2013.

Flask version is 3.0.2.
