MINOR: [Python] `Array.from_buffers` accepts `None` buffers (#49163)
### Rationale for this change
Fix the docs. It seems this is a feature and not just happens to work as
the code a little below even has an explicit comment:
https://github.com/apache/arrow/blob/0dfae701ef98aa4a26b9abbaaf3bf01130df3702/python/pyarrow/array.pxi#L1347
### What changes are included in this PR?
Document that `Array.from_buffers` takes a `list[Buffer | None]` instead of
strictly `list[Buffer]`.
### Are these changes tested?
*not applicable*
### Are there any user-facing changes?
Yes, but not in an API sense :)
