Marshmallow warnings: Use contextvars.ContextVar to pass context #40
Description
What's needed?
I see lots of warnings:
frequenz/quantities/experimental/marshmallow.py:270: RemovedInMarshmallow4Warning: The `context` parameter is deprecated and will be removed in marshmallow 4.0. Use `contextvars.ContextVar` to pass context instead.
