def parametrize_fixture_doc(*args):

Intended for use as a decorator for parametrized fixture,
this function will wrap the decorated function with a pytest
``parametrize_fixture_doc`` mark. That mark will format
initial fixture docstring by replacing placeholders {0}, {1} etc
with parameters passed as arguments.

Parameters:
----------
    args: iterable
        Positional arguments for docstring.

Returns:
-------
documented_fixture: function
    The decorated function wrapped within a pytest
    ``parametrize_fixture_doc`` mark
