QST: How should copy behaviour work in ArrowString Array `to_numpy` method?
I was looking at the TODO's in the project and noticed one in the `to_numpy` method of the `ArrowStringArray` class.

https://github.com/pandas-dev/pandas/blob/9d77a5641a912833fc6459ad67ecd8900f9f9e95/pandas/core/arrays/string_arrow.py#L196-L205

From what I understand, it seems like we want to use the option as a way to do a deep copy of the values given in the array.

Would like to raise a PR for the same.
