Issue:
DOC: Fix docstring typo
### Pandas version checks

- [X] I have checked that the issue still exists on the latest versions of the docs on `main` [here](https://pandas.pydata.org/docs/dev/)


### Location of the documentation

https://github.com/pandas-dev/pandas/blob/main/pandas/core/series.py

### Documentation problem

The docstring for the __arrow_c_stream__ method in the Series class uses the word "behaviour".

### Suggested fix for documentation

Suggested to rewrite as "behavior", which is the American English spelling, to maintain consistency with the rest of the Pandas codebase.
