fix the wandb logging issue

[ZIYU-DEEP]

What does this PR do?

Fixes #33320.

The existing error handling for wandb misses ConfigError when attempting to change the number of parameters, thus still blocking training; just added ConfigError to fix.

Duplicate of #33440?

[ZIYU-DEEP]

ooooh same issue. the implementation difference is that ConfigError does not depend on self (cf., #33440 (comment)).

[vasqu]

Is it guaranteed that we have access to the wandb pkg in the file? If so, I'd also appreciate your variant of doing it by top-level import. Maybe you can help out with the other PR so that we can concentrate our focus on one :)

[vasqu]

Ohh whoops, ig the import can't be seen in __init__ for the subsequent use (at least by the linter used here).

Guess it has to be moved into setup after we guarantee the successful import of wandb, i.e.

transformers/src/transformers/integrations/integration_utils.py

Lines 804 to 806 in bbef91a

	if self._wandb is None:
	return
	self._initialized = True

So based on self._initialized / after passing the first check that wandb is not None, it would be safe to import then.

Thanks!

There are a few code quality issues as @vasqu mentions above and can be seen in the code quality check; please fix those and I'll merge the PR.
