[MINOR][PYTHON] Remove deprecated use of typing.io

### What changes were proposed in this pull request?
Use `typing.BinaryIO` instead of `typing.io.BinaryIO`. The latter is deprecated and had questionable type checker support, see python/cpython#92871

### Why are the changes needed?
So Spark is unaffected when `typing.io` is removed in Python 3.13

### Does this PR introduce any user-facing change?
No

### How was this patch tested?
Existing unit tests / every import of this module

Closes #41084 from hauntsaninja/patch-1.
