Fix swanlab global step

[Zeyi-Lin]

What does this PR do?

A tiny fix to make the curves displayed by the swanlab logger align with the actual steps, provide a better experience for developers

Before this PR, if you set logging_steps to 5, the points in the line chart on SwanLab would still be spaced 1 step apart (without passing the step parameter in swanlab.log) 💦; after the modification, the points are spaced 5 steps apart, consistent with logging_steps 🎉

---

This pull request includes a minor change to the logging functionality in the on_log method within the integration_utils.py file. The change ensures that the global step is included in the logging calls for better tracking and consistency.

Logging improvements:

• src/transformers/integrations/integration_utils.py: Modified the on_log method to include the step parameter in calls to self._swanlab.log for both single value scalars and non-scalar logs.
