fix: Added logging.LoggerAdapter to _MaybeLogger union

The docs say about `logging.LoggerAdapter`:

<blockquote>

An easy way in which you can pass contextual information to be output along
with logging event information is to use the [`LoggerAdapter`](https://docs.python.org/3/library/logging.html#logging.LoggerAdapter) class.
This class is designed to look like a [`Logger`](https://docs.python.org/3/library/logging.html#logging.Logger), so that you can call
[`debug()`](https://docs.python.org/3/library/logging.html#logging.debug), [`info()`](https://docs.python.org/3/library/logging.html#logging.info), [`warning()`](https://docs.python.org/3/library/logging.html#logging.warning), [`error()`](https://docs.python.org/3/library/logging.html#logging.error),
[`exception()`](https://docs.python.org/3/library/logging.html#logging.exception), [`critical()`](https://docs.python.org/3/library/logging.html#logging.critical) and [`log()`](https://docs.python.org/3/library/logging.html#logging.log). These methods have the
same signatures as their counterparts in [`Logger`](https://docs.python.org/3/library/logging.html#logging.Logger), so you can use the
two types of instances interchangeably.
