Config realize bugfix

[maddenp-noaa]

Synopsis

Consider the following reasonable thing you might want to do via the uwtools API (in particular, this might be useful in a loop to apply multiple updates to a base config initially represented as a dict, after which a YAMLConfig, NMLConfig, etc. might be instantiated with this built-up dict to write the final config to disk in the desired format):

import uwtools.api.config as config
cfgdict = config.realize_to_dict(input_config={"a": "apple"}, update_config={"b": "banana"})

Currently, this is the result:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/maddenp/git/uwtools/src/uwtools/api/config.py", line 162, in realize_to_dict
    return _realize(**{**locals(), "output_file": Path(os.devnull), "output_format": None})
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: realize_config() got an unexpected keyword argument 'stdin_ok'

This is due to a bug in how realize_to_dict() is implemented. While fixing the proximate bug, however, I discovered a few other updates needed to support operations on in-memory dict objects, which I think will be a natural thing for API users to want to do. These are annotated via inline PR comments. After the updates:

>>> import uwtools.api.config as config
>>> cfgdict = config.realize_to_dict(input_config={"a": "apple"}, update_config={"b": "banana"})
>>> cfgdict
{'a': 'apple', 'b': 'banana'}
